The Essential Character of the Neutrino Mechanism of Core-Collapse Supernova Explosions

Understand

Calibrating with detailed 2D core-collapse supernova simulations, we derive a simple core-collapse supernova explosion condition based solely upon the terminal density profiles of state-of-the-art stellar evolution calculations of the progenitor massive stars.

• This condition captures the vast majority of the behavior of the one hundred 2D state-of-the-art models we performed to gauge its usefulness.
• The goal is to predict, without resort to detailed simulation, the explodability of a given massive star.
• We find that the simple maximum fractional ram pressure jump discriminant we define works well ~90% of the time and we speculate on the origin of the few false positives and false negatives we witness.
