Probing Strong Field $f(R)$ Gravity and Ultra-Dense Matter with the Structure and Thermal Evolution of Neutron Stars

Martín Nava-Callejas, Dany Page, Mikhail V. Beznogov

Thermal evolution of neutron stars is studied in the $f(R)=R+\alpha R^2$ theory of gravity. We first describe the equations of stellar structure and evolution for a spherically symmetr…
