A new class of solutions of compact stars with charged distributions on pseudo-spheroidal spacetime
Abstrak
In this paper a new class of exact solutions of Einstein’s field equations for compact stars with charged distributions is obtained on the basis of pseudo-spheroidal spacetime characterized by the metric potential grr=1+Kr2R21+r2R2$g_{rr}=\frac{1+K\frac{r^{2}}{R^{2}}}{1+\frac{r^{2}}{R^{2}}}$, where K$K$ and R$R$ are geometric parameters of the spacetime. The expressions for radial pressure (pr$p_{r}$) and electric field intensity (E$E$) are chosen in such a way that the model falls in the category of physically acceptable one. The bounds of geometric parameter K$K$ and the physical parameters p0$p_{0}$ and α$\alpha$ are obtained by imposing the physical requirements and regularity conditions. The present model is in good agreement with the observational data of various compact stars like 4U 1820-30, PSR J1903+327, 4U 1608-52, Vela X-1, SMC X-4, Cen X-3 given by Gangopadhyay et al. (Mon. Not. R. Astron. Soc. 431:3216, 2013). When α=0$\alpha = 0$, the model reduces to the uncharged anisotropic distribution given by Thomas and Pandya (arXiv:1506.08698v1 [gr-qc], 2015).
