Episode 366 - The YORP Effect, Star Brawls and Solar wind

What happens when stars brawl? What do they leave behind? When stars are dying they take down everything and everything around them from asteroids to other stars. What is the YORP effect? How do some tiny solar particles destroy an asteroid? Spiraling out of control, asteroids get YORP-ed at the end of a star's life. When a star gets to the end of it's life, it may swell in size, taking out asteroids and nearby stars. H. Olofsson, T. Khouri, M. Maercker, P. Bergman, L. Doan, D. Tafoya, W. H. T. Vlemmings, E. M.
