Relativistic superdense star models of pseudo spherodical space-time

Abstract

The physically viable models of compact stars like SAX (J1808.4-3658) can be obtained using Vaidya-Tikekar ansatz prescribing spheroidal geometry for their interior space-time. We discuss here the suitablitiy of an alternative ansatz in this context. The models of superdense star are proposed using a general three parameter family of solutions of relativistic field equations obtained adopting the altenative ansatz. The set up is shown to admitt physically viable models of superdense stars and strange matter stars such as Her. X-l.
