In this study, a simple cooling model of white dwarf stars is analyzed in Palatini f(R) gravity. It is found that modified gravity affects the structures and ages of white dwarfs, resulting in super-Chandrasekhar white dwarfs requiring more time to cool down compared to sub-Chandrasekhar ones or Newtonian models.
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.
