Wormhole solutions in f(R,T) = R + αR2 + βlnT gravity

Abstract

In this paper, the Morris–Thorne wormholes are studied in the background of [Formula: see text] gravity, where [Formula: see text] and [Formula: see text] are constants. The wormhole solutions are derived in two cases with different assumptions for the matter forms. In each case, the null energy condition (NEC) is analyzed and the range of parameters satisfying the NEC are determined. Further, the stability of solutions is examined with the help of the generalized Tolman–Oppenheimer–Volkoff (TOV) equation.
