摘要
The present paper reports a class of new solutions of charged fluid spheres expressed by a space time with its hypersurfaces t=const. as spheroid for the case 0 < K < 1 with surface density 2x10(14) gm/cm(3). When the Buchdahl's type fluid spheres are electrified with generalized charged intensity and it is utilized to construct a super-dense star and found that star satisfies all reality conditions except the casual condition for 0 < K <= 0.05. The maximum mass occupied and the corresponding radius have been obtained 8.130871 M (I similar to) and 24.60916 km respectively. Further, the redshift at the centre and on the surface are noted by z (0)=0.933729 and z (a) =0.383808 respectively.
