In 1985 the UA Theoretical Astrophysics Program (TAP) was created based on the shared vision of Jack (Randy) Jokipii and the then-heads of the astronomy, physics, and planetary sciences departments. The aim was to combine evident faculty and departmental strengths to create a theoretical program that would complement the UA’s recognized strengths in observational astronomy and planetary sciences. Since inception, the State of Arizona has continued to provide annual funding which has supported development of this tightly integrated program and increased the growth and visibility of UArizona’s leadership in the area of theoretical astrophysics.
The Departments of Astronomy, Physics, and Planetary Sciences form the Theoretical Astrophysics Program along with key partnerships with Applied Mathematics and the National Optical Astronomy Observatory -NOAO. Membership is open to UA faculty, research partners, postdocs, and grad students interested in the field of theoretical astrophysics.

TITLE:
Coronal Heating and Solar Wind Acceleration: What are we Learning from Parker Solar Probe
ABSTRACT:
The solar corona is a magnetized plasma at temperatures above a million degrees expanding into interplanetary space through the solar wind, which fills our solar
system by generating the heliosphere. Although decades of remote and in-situ
observations have enabled significant progress in our understanding of the solar
corona and solar wind dynamics, the mechanisms underlying coronal heating and
solar wind acceleration remain a fundamental unanswered question in space
plasma physics and, more generally, in astrophysics. The NASA mission Parker
Solar Probe was launched in 2018 with the objective of finding answers to these
questions by gathering fields and particle data at distances closer to the sun than any previous spacecraft. In this lecture, I will present some results from Parker
Solar Probe and discuss emerging perspectives on the role of waves and
turbulence in solar wind dynamics.

Dr. Anna Tenerani is Assistant Professor at the Department of Physics at the
University of Texas at Austin. Prior to joining the University of Texas in January 2019, Anna held a Caltech postdoctoral position at the Jet Propulsion Laboratory,
before continuing as a research scientist at UCLA. Dr. Tenerani’s research
interests lie in foundational research in nonlinear dynamics and turbulence in
magnetized plasmas, plasma instabilities, and magnetic field reconnection, with
applications to non-collisional plasmas and space plasmas.

Perihelion 22 coming up for Christmas Eve.
The lower the metallicity of a star, the more likely it's filled with sub-Neptunes and super-Earths. The presence of a cold giant planet causes the orbits of the inner planets to be less stable, thus favoring a smaller size. Ceres is the most stunted by Jupiter. One of the peculiar things about the Sun is that it has very high metallicity.
I like how he dismantles all fine tuning arguments especially in regards to the evolution of our own universe and I believe he is the only one who seriously and scientifically deals with this fine tuning aspect of physics in any meaningful and productive way. That's how philosophy and science can combine and co-exist to give insights into the fundamentals of our reality

First 20 minutes is an update on the search for Planet 9. The rest is interesting too but is on a whole other level :-)
thanks, skipping to 20. 😊
Wow, there is seriously nothing more boring compared to this presentation, other than the monotone nerd that introduced it. Planet 9 is a hugely relevant subject, and you fuckers don't have a clue what it takes to get people to watch stuff on UA-cam. What a goddamned shame... Audio: Fail. Video: D-. Hosting: Fail. Script: B+, and that's only because the what's-his-bucket math savant rain-man guy who did all this work has done this presentation 20 times already. Epic, epic fucking fail.... What a damned shame. You geniuses just squandered an opportunity... Refresh my memory, nobody gets into CalTech with an SAT below 1560? Is that right?
