Radial oscillations and stability of compact stars in $f(R,T)=R+2\beta T$ gravity

Juan M. Z. Pretel, Sergio E. Jorás, Ribamar R. R. Reis +1

We examine the static structure configurations and radial stability of compact stars within the context of $f(R,T)$ gravity, with $R$ and $T$ standing for the Ricci scalar and tra…
