Kelly Lepo (kellylepo@astrodon.social)'s status on Tuesday, 21-Jan-2025 01:35:13 JST Kelly Lepo
And wrapping up my #AAS245 posts - Day 4
We started off the morning with Stella Offner's plenary Lecture: The Star Formation Engine.
Offner is part of the STARFORGE collaboration, which simulates the star formation process.
Star formation involves a lot of physics at a lot of scales — from gravity, magnetic fields, and turbulence that influence how gas collapses into stars, and stellar feedback processes that destroy the surrounding nebula.
