Dynamics of Bianchi Type-III models with time-dependent gravitational and cosmological constants

Bhagwat Thakran, Praveen Kumar Dhankar, Seema Raut, Safiqul Islam

Published Online: 01 Nov 2025DOI: 10.47974/JDSGT-2025-01001

In this paper: We analyze the Einstein field equations with variable cosmological and gravitational constants, in the context of a Bianchi type-III universe filled with a perfect fluid. Here the tacit assumption is...

Gravitational Model of Compact Spherical Reissner-Nordström-Type Star Under f(R, T) Gravity

Safiqul Islam, Praveen Kumar Dhankar

Published Online: 02 Jan 2021DOI: 10.1080/1726037X.2021.1965705

In this paper: We present the interior solutions of distributions of charged fluid inside a sphere in f (R, T) gravity and which admits the existence of conformal Killing vectors. The charged sphere is embedded in a...
