Abstract |
The Finch and Skea spacetime produces stars which are physically reasonable. In this investigation we use a particular solution of the generalised Finch and Skea model of Maharaj et al. (Int. J. Mod. Phys. D 26:1750014, 2016) to study the mass and radius. We generate masses and radii for three cases: charged anisotropic, charged isotropic and uncharged isotropic distributions for observed compact objects. Physical features of the model show the non-negligible influence of charge and anisotropy on the mass and radius within the stellar objects. The model parameters values are fixed based on physical requirements and stability conditions of compact stars. We show that the model is consistent with the observed masses of selected pulsars PSR J1614-2230, PSR J1903+0327, 4U 1820-30, Cen X-3, EXO 1785-248 and LMC X-4. The investigation reveals that the Finch and Skea geometry is physically relevant for the study of observed compact stars. |
