Cornell Department of Astronomy & Space Sciences Fall 2021 Colloquium Series

Thursday, September 30, 2021 at 4:00pm to 5:00pm

Space Sciences Building, 105

"What Happens When a Massive Star Fails (Sort of) to Explode?"


There are observational and theoretical reasons to suspect that up to 10s of percent of massive stars that undergo core-collapse at the end of their lives fail to explode in a canonical energetic supernova explosion.  In this talk I will describe what transpires in such nominally failed supernovae and its importance for understanding the masses and spins of black holes (e.g., detected by LIGO).  I will also describe how 'failed' supernovae may manifest themselves observationally in time-domain surveys.

Dial-In Information
