  • Cooling Process of White Dwarf Stars in Palatini f(R) Gravity 
    Kalita, Surajit; Sarmah, Lupamudra; Wojnar, Aneta (MDPI, 2022-12)
    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 ...
  • Metric-affine effects in crystallization processes of white dwarfs 
    Kalita, Surajit; Sarmah, Lupamudra; Wojnar, Aneta (American Physical Society, 2023-02-28)
    We analyze the effects of modified gravity on specific heats of electrons and ions, Debye temperature, crystallization process, and cooling mechanism in white dwarfs. We derive the Lane-Emden-Chandrasekhar equation and ...
