In this work we investigate neutron stars (NS) in f( ,T) gravity for the case R+2λ , is the Ricci scalar and the trace of the energy-momentum tensor. The hydrostatic equilibrium equations are solved considering realistic equations of state (EsoS). The NS masses and radii obtained are subject to a jo...
