2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/12171We study the diffusive transport of neutrinos in a newly born neutron star to explore its sensitivity to dense matter properties. Energy and lepton number which are trapped during the catastrophic implosion diffuse out on the time scale of a few tens of seconds. Results for different dense matter models are presented.5 pages.
