Cooling Process of White Dwarf Stars in Palatini $f(R)$ Gravity
arXiv:2209.02095 · doi:10.3390/universe8120647
Abstract
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.
