« Asymmetric explosion of core collapse supernovae » |
T. Foglizzo |
The explosion of most massive stars depends on the revival of a stalled shock, a few hundred milliseconds after the birth of the central neutron star. Recent numerical simulations suggest that this revival is possible through an asymmetric explosion induced by a hydrodynamical instability named SASI. Its asymmetric character is also able to influence the kick and the spin of the resulting neutron star. I will review the current status of these discoveries, and describe the advective-acoustic mechanism at work behind SASI. |
