Progenitor dependence of neutrino-driven supernova explosions with the aid of heavy axionlike particles

We perform spherically symmetric simulations of core-collapse supernovae with the aid of heavy axionlike particles (ALPs) which interact with photons and redistribute energy within supernova matter. We explore a wide ALP parameter space that includes MeV-scale ALP mass ${m}_{a}$ and the ALP-photon coupling constant ${g}_{a\ensuremath{\gamma}}\ensuremath{\sim}{10}^{\ensuremath{-}10}\text{ }\text{ }{\mathrm{GeV}}^{\ensuremath{-}1}$, employing three progenitor models with zero-age main-sequence mass of $11.2{M}_{\ensuremath{\bigodot}}$, $20.0{M}_{\ensuremath{\bigodot}}$, and $25.0{M}_{\ensuremath{\bigodot}}$. We find a general trend that, given ${m}_{a}\ensuremath{\lesssim}300\text{ }\text{ }\mathrm{MeV}$, heavier ALPs are favorable for the shock wave to be successfully revived, aiding the onset of the neutrino-driven explosion. However, if ALPs are heavier than $\ensuremath{\sim}400\text{ }\text{ }\mathrm{MeV}$, the explosion is failed or weaker than that for the models with smaller ${m}_{a}$, because of an insufficient temperature inside the supernova core to produce heavy ALPs. The maximum temperature in the core depends on the initial progenitor structure. Our simulations indicate that the high-temperature environment in the collapsing core of massive progenitors leads to a significant impact of ALPs on the explodability.
