Radiation hydrodynamics of core-collapse supernovae: the "key" asset for a self-consistent modelling of these events

TL;DR

This paper introduces a specialized relativistic radiation-hydrodynamics code designed to simulate core-collapse supernovae, aiming for self-consistent modeling of observables like light curves and spectra to improve understanding and standardization.

Contribution

The authors developed a tailored relativistic radiation-hydrodynamics code for simulating core-collapse supernovae, enabling self-consistent modeling from progenitor to post-explosion phases.

Findings

The code successfully reproduces key supernova observables.

Simulations suggest potential for standardizing hydrogen-rich CC-SNe.

Implications for a 'CC-SNe Laboratory' for comprehensive event modeling.

Abstract

We have developed a specifically tailored relativistic, radiation-hydrodynamics Lagrangian code, that enables us to simulate the evolution of the main observables (light curve, evolution of photospheric velocity and temperature) in core-collapse supernova (CC-SN) events. The code features, some simulations as well as the implications of our results in connection with a possible "standardization" of the hydrogen-rich CC-SNe are briefly discussed. The possible role of this code in the development of a "CC-SNe Laboratory" for describing the evolution of a CC-SN event in a "self-consistent" way (from the main sequence up to the post-explosive phases) from a model/data comparison of light curves and spectra is also addressed.
