An updated proto-neutron star neutrino emission model

Relatore

Ballelli, Matteo (GSSI)

Descrizione

We present an improved parametric model for neutrino emission from core-collapse supernovae that directly connects neutrino luminosity and average energy to stellar properties during the emission. Our model incorporates two critical physical processes: convection within the proto-neutron star (PNS) and the evolving dynamics of neutrinosphere radii during the early emission phase. Crucially, the evolution of the PNS radius is tied to its gravitational-wave signature, providing a stronger physical framework for joint neutrino and gravitational-wave searches of the next Galactic supernova.
