Description
In this talk, I will present a novel scheme to classify the oscillation modes of a newly born proto-neutron star surrounded by a stalled accretion shock in core-collapse supernovae (CCSNe). Our classification is physically motivated, as it is based on the energy of the restoring forces of the mode. We investigate the nature of the modes by considering the different regions of the CCSN that they stem from. In that way, we find that there are different families of p- and g-modes in the system, living in different areas. Our analysis paves the way to systematic studies for parameter inference of the PNS properties from future gravitational wave signals.
