Asymmetric explosion of core collapse supernovae
Abstract
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 helped by a hydrodynamical instability named SASI. Its asymmetric character is also able to influence the kick and the spin of the resulting neutron star. We review the current status of these discoveries, and describe the advective-acoustic mechanism at work behind SASI.
