Constraints on Core-Collapse Supernova Theory
Abstract
Core-collapse supernova theory predicts that some massive stars explode and some fail to explode forming black holes. In this talk, I will summarize the theory of CCSN explosions and present observational constraints. In particular, we compare the inferred explosion energies from simulations and observations. We find that the simulations are a factor of 2 to 10 times less energetic than the observations. However, both the simulations and observations are biased, and we discuss way to mitigate this bias. In addition, we age-date the stars around 300 SNRs in M31, M33, and M83. From these ages, we infer the progenitor masses for the stars that exploded. With hundreds of progenitor masses, we infer basic parameters of the progenitor distribution. We infer the minimum mass for explosion to be 7.3±0.1 solar masses, the maximum mass is greater than 59 solar masses, and the power law distribution between these limits is -2.95(+0.45/-0.25).
