Cooling Process of White Dwarf Stars in Palatini f(R) Gravity

Abstract

A simple cooling model of white dwarf stars is re-analyzed in Palatini (Formula presented.) gravity. Modified gravity affects the white dwarf structures and consequently their ages. We find that the resulting super-Chandrasekhar white dwarfs need more time to cool down than sub-Chandrasekhar ones, or when compared to the Newtonian models. © 2022 by the authors.
