Analytic approach to axion-like-particle emission in core-collapse supernovae

We investigate the impact of a presumed axion-like-particle (ALP) emission in a core-collapse supernova explosion on neutrino luminosities and mean energies employing a relatively simple analytic description. We compute the nuclear Bremsstrahlung and Primakoff axion luminosities as functions of the protoneutron star (PNS) parameters and discuss how the ALP luminosities compete with the neutrino emission, modifying the total PNS thermal energy dissipation. Our results are publicly available in the python package ARTISANS, which can be used to compute the neutrino and axion observables for different choices of parameters.

We investigate the impact of a presumed axion-like-particle (ALP) emission on neutrino luminosities and mean energies in a core-collapse supernova explosion using a simple analytic description. We calculate the nuclear Bremsstrahlung and Primakoff axion luminosities and discuss how the ALP luminosities compete with neutrino emission, affecting the total thermal energy dissipation of the protoneutron star (PNS). Our results are publicly available in the python package ARTISANS for computing neutrino and axion observables under different parameter choices.
