Drama Preceding the Deaths of Massive Stars

Learn about groundbreaking research in massive star astrophysics through this physics lecture that explores end-of-life stellar processes, their influence on supernovae, and resulting compact remnants. Delve into new models explaining mass loss from red supergiants through shock wave-supported chromospheric material, providing insights into type II-P supernovae observations. Examine how expanding low-mass helium stars interact with binary companions to create type Ibn supernovae, and discover new calculations predicting lower black hole spins from high-mass helium star collapse. Explore the intersection of asteroseismology, supernovae studies, and gravitational wave observations driving current advances in understanding massive stellar evolution and death.
