# The Antesonic Condition for Core-Collapse Supernovae

### Abstract

While the neutrino mechanism is understood to be the driving force behind core-collapse supernovae (CCSNe) explosions, the physics of this mechanism in multidimensional simulations are not fully understood. We extend the “antesonic condition” formulated by Pejcha & Thompson (2012) to time-dependent, polytropic models. We find that high spatial resolution is necessary for accurate determination of simulation properties near the critical curve, and low resolution simulations explode less readily. We also find that there is an important physical connection between the critical mass accretion rate at explosion and the mass loss rate of the post-explosion wind.

I use analytic and computational methods to study the supernova explosion mechanism and the magnetocentrifugal winds of newly born neutron stars.
