Cooling process of brown dwarfs in Palatini f(R) gravity

Year: 2021

Type: article

Abstract: We present an analytical model for the evolution of brown dwarfs in quadratic Palatini $f(\mathcal{R})$ gravity. We improve previous studies by adopting a more realistic description of the partially degenerate state that characterizes brown dwarfs. Furthermore, we take into account the hydrogen metallic-molecular phase transition between the interior of the brown dwarf and its photosphere. For such an improved model, we revise the cooling process of substellar objects.
