Gravitational Wave Eigenfrequencies from Neutrino-Driven Core-Collapse Supernovae

Understand

Core-collapse supernovae are predicted to produce gravitational waves (GWs) that may be detectable by Advanced LIGO/Virgo.

• These GW signals carry information from the heart of these catacylsmic events, where matter reaches nuclear densities.
• Recent studies have shown that it may be possible to infer properties of the proto-neutron star (PNS) via gravitational waves generated by hydrodynamic perturbations of the PNS.
• However, we lack a comprehensive understanding of how these relationships may change with the properties of core-collapse supernovae.
