Title: The Deaths of Massive Stars
Abstract:
A commonly-held view is that stars born with masses above ~8Msun will die as supernovae (SNe) and leave behind a neutron star, whereas stars above some higher mass threshold (~30Msun) will leave behind a black-hole (BH) with little or no SN. However, there have been recent claims that the mass threshold for BH production is much lower (~17Msun). This would have important ramifications for other areas of astrophysics through its influence on the cosmic SN and BH production rates. In this talk I will take a critical look at the evidence for this result, and reappraise the mass threshold for BH production.
