Anisotropic charged strange stars in Krori-Barua spacetime under [formula omitted] gravity.

We present spherically symmetric anisotropic charged strange stars under the framework of f (R , T) gravity. For this we consider that the Lagrangian density is a linear function of R and T where R is the Ricci Scalar and T represents the trace of the energy–momentum tensor. These stars are considered to be built with Strange Quark Matter (SQM) distribution. To describe this SQM distribution inside the stellar bodies, we incorporate the simplest form of phenomenological MIT bag model equation of state (EOS) p r = 1 3 (ρ − 4 B g) , where p r is the radial pressure, ρ is the energy density and B g is the bag constant. To determine density and pressure from the Einstein Field Equations (EFE), we use Krori-Barua (KB) metric and using the observed values of mass and radius for strange star candidates L M C X − 4 , we calculate the value of B g from our model. Comparing the interior metric with exterior Reissner-Nordström metric at the surface, we calculate the unknown parameters incorporating the observed values of the mass and radius, we find that the coupling constant χ affects the bag value significantly. The model shows consistency with all the physical conditions and presents a viable study to the nature of charged anisotropic massive stellar system. • We study anisotropic charged strange stars under f (R , T) gravity. • Physical parameters are calculated with the help of observed values of stars. • Bag constant reduces with the increasing value of coupling constant. • Solutions provide a stable non-singular model for strange stars.
