摘要

我们用一种相对简单的解析描述研究了在核坍缩超新星爆炸中假定的类轴子(ALP)发射对中微子光度和平均能量的影响。我们计算了质子中子星(PNS)参数对核轫致辐射和Primakoff轴子光度的影响，并讨论了质子中子星(ALP)光度如何与中微子发射竞争，从而改变了PNS的总热能耗散。我们的结果在python包ARtiSANS中是公开的，它可以用来计算不同参数选择下的中微子和轴子观测值。

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.
