Implication of f(ℛ,ℒm,𝒯 ) gravity on the anisotropic compact stars and mass-radius relations under NICER radii measurements of PSR J0740+6620

In this work, we have investigated the consequences happen to a configuration of a neutron star when gravity itself is modified by a non-minimal coupling between matter and geometry. Particularly, we explore a new exact analytical solution for anisotropic compact stars using the...

Investigations of Pseudo-Shouten symmetric spacetimes in f ( R )-gravity vacuum solutions

Pseudo-Schouten symmetric spacetimes are examined under a differential condition on the Schouten tensor, producing explicit relations for the scalar curvature, the Ricci tensor, and the associated covector field. It is shown that the associated covector is a Ricci eigenvector and...
