04/21/2017Astro SeminarEliot QuataertThe Surprisingly Dynamic Last Years in the Lives of Massive Stars [ -- Description ]

Description: In the last few years of the lives of massive stars, fusion in the core of the star produces a nuclear power that greatly exceeds the Eddington luminosity. This drives vigorous convection in numerous core and shell burning phases. I describe the surprising effect that waves excited by such convection can have on the properties of massive stars in the years leading up to core collapse. Wave transport of energy into the stellar envelope can power prodigious mass loss in the last year of stellar evolution. And angular momentum transport by waves excited during shell burning phases may well determine the angular momentum of the pre-supernova core, setting the birth spins of neutron stars and black holes.
