Gravitational waves and Supernovae — Lutz Köpke and •Alexander Fritz for the IceCube collaboration — Johannes-Gutenberg Universität Mainz, 55128 Mainz

While Supernovae release 99% of their energy in form of neutrinos and antineutrinos, they also exhibit different phases in which gravitational waves may be produced. IceCube is capable of detecting MeV-neutrinos from Supernovae using the inverse β-decay reaction. For a galactic Supernova at 10 kpc, IceCube will detect a few 100000 unresolved neutrino interactions. That leads us to the possibility to resolve fine structurs of time changes in the flux. In this presentation I am going to quantify correlation between the gravitational wave signal and the neutrino signal of Supernovae for a specific three dimensional simulation. Notably, correlations are seen in periods, where standing accretion shock instability (SASI) arise.
