Confront $$f(R,T)={\mathcal {R}}+\beta T$$ f ( R , T ) = R + β T modified gravity with the massive pulsar $${\textit{PSR J0740+6620}}$$ PSR J 0740 + 6620

Abstract Many physically inspired general relativity (GR) modifications predict significant deviations in the properties of spacetime surrounding massive neutron stars. Among these modifications is $$f({\mathcal {R}}, {\mathbb {T}})$$ f ( R , T ) , where $${\mathcal {R}}$$ R is the Ricci scalar, $$...
