An attractive method of obtaining an effective cosmological constant at the present epoch is through the potential energy of a scalar field. Considering models with a perfect fluid and a scalar field, we classify all potentials for which the scalar field energy density scales as a power law of the scale factor when the perfect fluid density dominates. There are three possibilities. The first tw...

In this article, we studied the behavior of relativistic spherical objects considering Tolman IV spacetime in modified f(R,T) gravity for uncharged perfect fluid matter. We have chosen matter Lagrangian as Lm=?p to develop our present model. particular, investigation reported compact object LMC X?4 [Mass=(1.04±0.09)M?; Radius= 8.301?0.2+0.2 Km] paper. The effect coupling parameter ? on local di...
