White dwarf stars in modified gravity

TL;DR

This paper explores how modified gravity theories can offer alternative explanations for white dwarf properties, including cooling, age, and mass limits, using a simple Lane-Emden model within Palatini $f( ext{R})$ gravity.

Contribution

It introduces a new approach to white dwarf physics using modified gravity, deriving the Chandrasekhar limit within Palatini $f( ext{R})$ gravity.

Findings

Modified gravity can explain white dwarf cooling and age.

Chandrasekhar limit derived from Palatini $f( ext{R})$ gravity.

Potential alternative to standard white dwarf models.

Abstract

A few questions related to white dwarfs' physics is posed. It seems that the modified gravity framework can be a good starting point to provide alternative explanations to cooling processes, their age determination, and Chandrasekhar mass limits. Moreover, we have also obtained the Chandrasekhar limit coming from Palatini $f(\mathcal{R})$ gravity provided by a simple Lane-Emden model.
