The Advective-Acoustic instability in type II Supernovae
P. Galletti, T. Foglizzo
The puzzle of birth velocities of pulsars (pulsar kicks) could be solved by an asymmetric explosion of type II Supernovae. We propose a simple hydrodynamical mechanism in order to…

Non-radial instability of stalled accretion shocks: advective-acoustic cycle
Thierry Foglizzo, Pascal Galletti
The linear stability of stalled accretion shocks is investigated in the context of core collapse of type II supernovae. We focus on a particular instability mechanism based on the…
