Cooling process of white dwarf stars in Palatini $f(R)$ gravity [CL]

http://arxiv.org/abs/2209.02095


A simple cooling model of white dwarf stars is re-analyzed in Palatini $f(R)$ 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.
