Constraining red supergiant mass-loss prescriptions through supernova radio properties

Supernova properties in radio strongly depend on their circumstellar environment and they are an important probe to investigate the mass loss of supernova progenitors. Recently, core-collapse observations have been assembled rise time peak luminosity distribution supernovae at 8.4 GHz has estimated. In this paper, we constrain mass-loss prescriptions for red supergiants by using Type II radio. We take de Jager van Loon rates supergiants, calculate based them, compare results with observed distribution. found that rate explains widely spread well, while predicts a relatively narrow range luminosity. conclude should strong dependence as reproduce supernovae.
