Surprise! Ancient Supernova Remnant Is a Bizarre Object We've Never Seen

[@George-rk7ts]

Supernovas will never cease to puzzle us. That's the best thing about them.
Nice work, Anton.

[@douglaswilkinson5700]

Dr. Jason Kendall has uploaded the his astronomy lecture notes and covers supernovae in detail.

[@chicojcf]

I'd add the qualifier: STARS will never cease to puzzle us.

[@willhandy5345]

This is fascinating. The universe seems endlessly willing to supply us with weirdness. I greatly appreciate your telling about some of it. 🙏🏼

[@Alondro77]

It probably crossed the stable mass threshold and partially collapsed, which triggered the carbon burn. But, it's already so small and dense that this carbon burn is going at a radically accelerated rate. It's probably also fusing other elements swiftly as well and producing all manner of odd isotopes due to the electron-degenerate matter making up the original white dwarfs. Portions of its core might even be being forced into neutron-degenerate matter by the extreme pressure and density, as this is a star that SHOULD be collapsing into a neutron star by its sheer mass alone.

[@RedRocket4000]

That was the big clue it not a white dwarf it was too heavy meaning something more was preventing collapse.

[@Flesh_Wizard]

me edging a white dwarf:

[@ReggieArford]

Centrifugal force is probably preventing its collapse, but allowing high enough temperatures to burn carbon, etc. Remember fusion is a product of pressure (density) and temperature. With enough temperature, the pressure doesn't have to be as high.

[@Alondro77]

@@ReggieArford The pressures are going to be outrageously high by default, as this object is the result of two stellar cores crashing together and just barely exceeding the Chandrasekhar Limit and managing not to totally collapse into a neutron star due to the sudden ignition of carbon fusing at a very high rate.
The mystery is what its fate will be. Since it's straddling that mass limit, if it has enough carbon to burn as it's losing mass from its immense stellar winds, it may just sink beneath the limit and eventually simply 'go out' and become a very heavy O-Ne white dwarf, rather than undergo a supernova.

[@andyf4292]

wonder if its spinning too fast to collapse properly?

[@laurachapple6795]

Textbooks always make stars sound so steady and predictable and it turns out in real life they just do whatever they want.

[@chicojcf]

True enough! Stars never needed permission to be as exoctic as they really are.

[@faster6329]

That is the standard model for you. Seems like nothing is standard.

[@sneeringimperialist6667]

It's like a giant fusion bomb going off continuously . There's no certainty in any of it, just an average yield forced back by immense gravity...

[@Bob-of-Zoid]

They only do that which physics dictates, and they cannot not do it! As for textbooks: Well, 2D pictures.... I can see it, but some of the stuff shown in animations are literal representations of hundreds, thousands and even millions of years, and all of the color is often added, because they exist outside of the visual range. So all that and it's freaking Awesome to see it like that to aid in understanding.
Of course flat earthers and freaks who think stars are something totally different will claim "NASA faked it" when I would say "Hell yeah they did! How else could they make invisible light or a fine particle cloud that otherwise just looks like a gray smudge or something out of focus, visible and exciting so you can better wrap your head around it?" "Oh wait, obviously not your head Flurf, it seems defective"!

[@Bob-of-Zoid]

[@SteveSiegelin]

Remember that we're also looking for a supernova possibly to show up in September 2024. I forget what star exactly but it's in the Hercules constellation. If they get the date clothes like they think they did this will be the first time we've been able to predict when a supernova is light will reach us. It's supposed to be visible to the naked eye for a week.

[@ReggieArford]

@@SteveSiegelin It's a "regular" nova, t Corona Borealis, and it goes off every 80 years or so. AP has already done a video about it; also Dr. Becky & others.

[@SteveSiegelin]

@@ReggieArford it's still a Nova, I might have accidentally said a supernova but it's the same basic principle as what's going on in the video as it is a binary star. Eventually they will go supernova but you are correct. My whole point was to let people know that didn't already know. Some people may have missed it.

[@edreusser4741]

I would like to be the very first to predict the existence of the Reusserburg certainty principle. This predicts that the more people expect that a given specific star will explode into a Nava or Supernova the less likely that even is to occur. The probability of a supernova occurring is inversely proportional to the number of people watching for it. This is a variation of the watched pots and boiling family of stupid sayings.

[@arieverhoeff9141]

problem is no side is sure if they are right. Betelgeuse could have been supernova, but because light doesn't go faster as c, we will only notice when the 'supernova light' reaches us.
At this moment everybody who says Betelgeuse has gone supernova could be right, and everybody who says it hasn't could be right too. I'm not sure if more people watching Betelgeuse think it has gone supernova (which in your statement means it hasn't) or if more people think it hasn't ( which would imply it has, according to your Reusserburg certainty principle).
Matter of fact is our human life spans do not compare to these astronomical timescale. (which leaves a lot of room for grifters and people who just say something because they're influential in their group and no one can say for sure they're wrong)

[@richardt74]

What if none us look? It could stay in superposition for eternity.

[@stevejohnson3357]

Or just Reusserberg's law. The likeliest candidate is Betelgeuse but while it could have already gone off, for us it hasn't and in the meantime, something else will have happened based on some physical property we don't know about.

Here is a question; What is the physics, that gets neutron stars spinning so fast? It takes our sun just over 26 days to make on rotation, what is the forces that gets neutron stars spinning at 716 times a second? What is the force that makes them spin fast and how is that force exerted to create a spinning motion?

Hi Anton, around @6:40 you mentioned the ionisation of radioisotopes preventing their radioactive decay. I've never heard of this effect, can you tell us more? I have been led to believe that only time dilation effects can impact the decay rate of radioisotopes.

[@stargazer5784]

Ionizing radiation impacts nuclear processes, which in turn affects nuclear decay rates. Published decay rates are for isotopes in a relatively benign environment.

[@quentinparker5743]
