Anyone else here giggle at FU Orionis?🤭
Yes! Though in my defense: also just a bit drunk.
These stars are really FIRED UP. What were you thinking 🤔
Oh grow up😂
Affirmative 😊
@@Justasmalltownokie In my defense, I was absolutely not drunk. Or high, for that matter. Funny things are funny, and the last thing I want in life is to grow into a Grinch.
I know why its named FU Orionis but it sounds like they just named it that because they were annoyed at how confusing it was. FU Orionis!
FU Orionis! (while dramatically shaking their fist at the sky)
Hahaha i had same idea lmao.
Do you really understand Classical Latin grammar?
FU. That's not very nice. 😈
:) Old astronomers tend to yell at stars, not clouds like the average civilian...
I'm always astonished how well you prepare these videos. You cover all the angles and keep the golden thread throughout. Well done and hats off from a fellow physicist.
And he does one of these every single day. It’s admirable.
it's because he can read and has at least the cognitive capacity of a 9 year old child.
it's not actually impressive unless you're fairly severely cognitively impaired.
Seriously- this is next level talent, particularly for churning them out on a daily basis! One could be forgiven for expecting quality to suffer at that pace, but he manages to avoid AI clickbait altogether, and his scripts are always concise, accessible, and fascinating.
Definitely a one of a kind channel.
Judging by their names I'd say astronomers don't care for these types of stars...
The IAU in Paris has the authority to name and approve names.
I think its bang out of order. Degeneracy rising. That they went with it says a lot.
@@douglaswilkinson5700Woosh
🤣🤣🤣... fu star.s (because you are out of the norm 😒)
Aaaaauuugggghhh so much brighter, my eyes! FU star
Astronomer: FU Orionis.
Orionis: What did I do?
Um...
> Astronomer: FU Orionis.
> Orionis: What did I do?
> *Translate to English*
:) "You know what you did, Orionis!"
Never thought I'd hear Anton say FU haha
Damn what did Orionis do?
Orion-is is a 3rd declension genitive singular Latin noun. The -is mean "of Orion."
@@douglaswilkinson5700 Woosh
That's a common everyday dude. I don't understand a lot of stuff but I love watching these videos
lol Me too. It doesn't take long for me to "lose the thread".
Wonderful as always Anton. Thank you. 🙏😊
Thank you for this video about a class of stars I am more familiar with. Reminds me of the early years of taking my telescopes out under the night sky.
You rock Anton!
I love how every day something out there somewhere is redikkaliss! 😊
My theory that Mercury was once a gas giant core gains even more relevance. O^O
The core of something!
@@efdangotuyes. The core of a gas giant planet that existed way in the solar system's past.
Always leave a like for Anton
If had teachers more like Anton when I was in high school, I may have actually paid attention long enough to graduate... 😕
I had a super doctor in physics. The man was amazing. I wish i could find him 😔
UA-cam videos is not thr same as learning deeply in school. Try not to compare thr two
If you are watching Anton's videos, you are learning a lot. The fact that you are doing this because you enjoy learning, it's obvious that public education massively failed you, as it did many people. I had the good fortune to have had a good public school education, when most parents cared greatly about their children's education, before the United States Department of Education in 1979.
This is entertainment though. Education is a completely different beast. If you are in the USA though, we do have really low ranked education system compared to the rest of the first world.
Can I get an AAAAAAAAMEN!!
Well FU too, Orionis!
They should call these planets 665, the neighbors of the beast.
666 represents Emperor Nero. Koine Greek's alphabet was used for words and numbers.
lol Everything in space is EXTREME and extremely WEIRD! Thanks Anton.
Cool. Thanks for sharing.
😮And some say they are happy for new discoveries.
0:27 I'm don't know where that valley is but the mountains have snow and it is a view of the Milky Way. Obviously, it is an earth scape.
Thank you Anton
F ME?
No, FU!
I'm not sure Anton is familiar with its various meanings in different cultures.
@@drbuckley1 Likely not. This seems like the kind of thing he likes to joke about.
Fascinating.
Incredible!
🤖 FU stands for "fantastic universe", right??? 😮
Wow , from ur description, I’m imagining a ring of accreting gas planet-like protostar material of which a Jupiter sized planet is just a kicked out drop.
Hello wonderful person.
Astronomers: "FU Orionis!"
Orionis: "Why?! It's growing pains, nothing else!"
I think there should be a comma; "FU, Orionis(!)"
Orionis broke somebodies heart.
Imagine hovering just above the surface of that star while all that was going on🤔
I am FU Orionis, destroyer of worlds!
These stars have been telling us off for a while.
How does dropping material onto a star make it brighter?
The more mass a star has the greater the rate and amount of fusion thus the greater its luminosity.
Could some of these variable stars actually be nearby red dwarfs with very low luminosity - say less than one tenth of one percent of the luminosity of the Sun such that what would create a small change in luminosity of a more massive star would increase the luminosity by several fold?
is it true that normally a dim red dwarf at the distance from us of the fairly nearby star "Sirius" cannot be seen with the naked eye (dimmer than magnitude 6) ?
Valid questions. Distances to well observed stars like this one (since 1937 at least) are pretty accurately determined using parallax measurements and other methods, so the chances of this star being way closer than described are pretty much nonexistent. As to the second question, there are no naked eye visible red dwarfs that I know of.
@@stargazer5784 Nearest star to us is Proxima Centauri, it's a red dwarf and it is 11th magnitude (~200 times fainter than naked eye can see). So, yes, no red dwarfs are visible to naked eye.
Do stars create planets or do planets collect around Stars
A star and it's planets typically form together from the same cloud of material. While a star might capture a rogue planet, such events are considered to be rare.
I am just surprised that there was no FU joke by Anton.
I wonder if there's a connection to Fu Orionis and FRBs
It’s unlikely this happened to the Sun, but it is interesting, the Sun is a VERY stable star so unless there was a collision… But who knows?
Anton misspoke at 7:09. "Magnetic force" is a misconception, like centrifugal force. If anything, it would be electric force.
????? Magnetic forces absolutely exist. Technically they are just the equivalent of electric forces from a moving reference frame, but I promise you, they exist.
@@Nosirrbro Really? Then explain that in terms of Maxwell's equations, and again in terms of QED.
@@existenceisillusion6528 I just finished a course on maxwells equations this spring so I can gladly explain that to you. I haven’t taken any quantum courses so I can’t give you any explanation there that is reliable, but as far as I’m aware the main difference is that since electrons have spin, they act equivalently to how an incredibly tiny loop of current would act under maxwells equations.
The equation for electromagnetic force is F=q(E+V cross B), where q is electric charge, E is the electric field, and B is the magnetic field. V is the velocity of the object with charge q. Thus, the force is present either when there is any electric field present at the location of a charged object, pointing in the direction of the electric field for a positive charge or the opposite direction for a negative charge (the sign of q would be negative in that case and thus the force would be negative). The other situation in which force is present is when the charged object is moving through a magnetic field, in which case the magnetic force is perpendicular to both the velocity and the electric field direction, indicated in the equation by the cross product between V and B.
It’s worth noting that a magnetic field is generated when an electric charge is moving, which is what makes the magnetic field in reality the same as the electric field from a moving reference frame. Really, it’s all the same electromagnetic field and electromagnetic force, but it’s useful to describe specific situations of that force and field as either magnetic or electric because they are present in different situations and behave differently.
In the case of electrons however, since we know they are quantum particles with spin, in maxwells equations, that behaves equivalently to a tiny loop of current, which means that the charge q would have some velocity V, so in a magnetic field B an electron will experience a force as per those equations.
I can’t explain this to you in terms of the equations of QED however, I started taking a class on partial differential equations but I dropped out before we got to the Schrödinger equation or anything like that, lol
Dope
Anton: ... FU Orionis ...
UA-cam: Demonetized!
FU or Uranus?
F Uranus 👁👄👁
I wish I had FU luminosity
This could imply many Hot Jupiters we find out there are just survivors of this process.
How do we know it was just not a gas cloud finally moving away from it? Or would that take longer for the increase in brightness?
Am I the only one who hears about the ways stars interact and think "I know people like that"?
I know it's mere anthropomorphism, but I find stars and their interactions with each other comparable in some ways to human relationships.
You know people that ate twenty of their infant children?
@@Nosirrbro Lol, no. To be fair, I did say comparable in some ways, not all.
@@Ann-snowshoeingonEnceladus what specifically reminds you of people in that way about this star if u don’t mind me asking? I’m genuinely interested
@@Nosirrbro That's an interesting question, I'd not really analyzed it much, but I guess they remind me of children, hungry and changing their luminosity as they evolve, and the disc interaction and corresponding higher accretion rate and outbursts kind of like teenagers, volatile and unpredictable. Then like young adults, they are rearranging their surroundings, tearing some things down and making dust that will one day rebuild things in a new way. If they grow into G or K type stars, they're similar to contented adults. Other kinds of stars do too, for example how some people live loud and bright but burn out early like blue and white giants, and binary stars that in some cases are destructive to one another, or one overpowers the other and eventually destroys it (reminds me of my first husband), and in other cases they live calmly near each other. Then there are stars orbiting black holes. I think we've all met someone who is a bit like a black hole, insatiable and draining, and best kept at a distance. I'm interested to hear your analogies on the subject, if you like, and thank you for asking!
Could mercury be the leftovers from a gas giant?
Our congress has no idea how we Americans are feeling, we individuals are fed up with this treasonous administration. I feel pity for our country. A lot of people are suffering to survive! I appreciate Gianna Everett! Imagine investing $2000 and receiving $6,500 in 4days.
You're right! The very first time i tried. I invited $1000 and after a week, I receive $10,000, that really helped us a lot to pay up our bills
Let's face it... Buying more stocks & index funds during stock markets are scary Which makes it really hard to do for mostly people like me. I have 260k want to transfer into an s&s isa but it's hard to bite the bullet and do it.
The key to financial stability is having the right investment suggestions for a diverse portfolio. Many investment failures and losses happen when you invest without proper guidance.
I'm favoured, $26K every week! I can now give back to the locals in my community and also support homeless and folk's with disabilities all thanks to Mr Larry Marshall
Investment has been the easiest means to save and multiply money because money left for saving ends up used without returns.
FU Orion! And you, too, sir! Those fightin' words are enough to make young stars kill and eat their own baby planets!
Young stars going through puberty are every bit as unpredictable as our own children! Who'da thought?
Thanks for the info, Anton!
So gas giants can be star food?
One of those images is actually not FU Orionis. It is a pre planetary nebula, and is a dying star, not a pre-main sequence stars
We are plasma beings living in a Plasma Universe. ✨
I always taught that peoplewho Giggle at the word Uranus were Immature, yet FU Orionis cracks me up every tie🤣🤣🤣
Fu Oriones, you know what you did
FU Orionis: "I ate a hot Jupiter."
1:33 Let's hope the algorithm and automod and new content-creator spoken word limitations gave you a pass on that one.
Sounds a lot like the helium flash to me, but im not a physicist so i could be very wrong.
I'm just glad my name isn't Orionis. 😮
Complicated🤔😊
I want to discover a star and name it Anton ❤
Stop it. Get some help.
❤️👍
solar flare or death ray from a death star?
Someone has a grudge on Orionis.
baby star toodoodoo doo baby star toodoodoo doo ba
🖕🖕 😂 arghhhh now I'm going to have that damn song stuck in my head for a while, again.
yknow what? FU. *turns 600x brighter*
Dang. Thought this was about Shirley Temple.
Talk about solar micronova , can Sun lose its outer shell and wipe out life on planet Earth?
Can binary stars have elliptical orbits?
Yes. Highly elliptical sometimes.
@@stargazer5784 Then that could have a strongly variable effect on the dust cloud, probably periodic.
Aliens obviously.
Why did the star suddenly get so bright and stay bright? Somebody left the lights on. 👋 😬
Quark novas.
No such celestial phenomena.
Fu Orionis!
Where is the star in relation to Betelgeuse?
The Dyson Sphere failed. Contractor has to worried.
Can you make a video outdoors once? I’ve only ever seen you with a green screen. Thanks.
can this happen to our sun?
I really miss your videos, please post them more often!
My brother in Christ, he posts everyday.
@@Auroral_Anomaly
Brother in Christ? 😂
What u talking about he posts everyday u obliviously don't look
@@Reno_Slim It’s a popular meme format, I’m not religious.
He literally posts every SINGLE day lmao. He’s only missed like 2 or 3 days in the last decade. Possibly the best record of any educational content creator alive.
Nice start... but I don't like the final explanation... Why always colliding binaries and destroyed planets? We understand the beautiful mechanics of the two-body system expansion... Tidal forces help to maintain the stability of the system rather than causing its destruction (Unless the Lagrange effect takes place with a 3rd body). The luminosity change explanation is more simple with a restructure of the atomic fuel cycle requiring a lattice change in the star. Spectrometry must also consider element and chemical emission lines rather than black body emission given such a lattice change. Cheers! 🙂
My first thought was that it is a new star that is just forming.
Would anyone around those pizar Star think there random arbitrary condition be required for life or advanced chemistry 🧪 ⚗️ becoming sentient then sabiant
FU? Who comes up with these names? FU.
I'm waiting for a slew of comments about that! 🤣

The Universe sure Loves to Consciously Communicate with the Rest of Itself.. when it Manifests itself into Physical Realms
HOPEFULLY WE DONT EXPERIENCE THAT....END of us ALL and ALL LIFE on this planet

Это возможно выполнить с помощью оптоволоконного ГИБРИД гироскопа. Вот исходя из выполненного на 100% опыта Майкельсона, возможно доказать постулаты: Свет - это упорядоченная вибрация гравитационных квантов и доминантные гравитационные поля корректируют скорость света в вакууме. (Мы не ищем эфир, мы увидим работу квантов гравитации)

FU Orionis! You still owe me $20z
The sun can't do this, right?....right?
No.
Hello Anton how will I become a star in a distant galaxy shining alone
Stars cannot go *nova!* Only dead white dwarfs that acrete gas from a partner then ignites surface fusion are novas.
Sorry. The FU kinda caused me to chuckle a bit.
No fu
F me?!
FU ...Orionis
Shame there soooooo much stuff potentially in the way of light to get here.
