Abstract:

This talk will focus on two somewhat unusual types of shock dynamics associated with core-collapse supernovae:

1. "Bells, not whistles": Some massive stars appear to undergo shock-driven outbursts before their cores collapse. I will show that nonlinear acoustics rules out a standard explanation for how these events are driven, a result that deepens the mystery of their origin.
