An Emerging Coherent Picture of Red Supergiant Supernova Explosions

We now know that the bulk of supernovae result from core collapse of red supergiants of modest initial mass about 8 to 16 solar masses However what happens to stars with somewhat higher masses is rather uncertain and is related to the puzzling mass distribution of compact remnants that is found Furthermore as embarrassing as it is simulations are so far struggling to produce models that robustly explode Yet supernovae seem to do it quite easily I will address these issu
