| Abstract : | Properties of nuclear matter at density beyond nuclear saturation density are not well understood. Compact star is unique laboratory to provide us with a plenty of information for studying such dense nuclear matter. According to Bodmer and Witten conjecture, strange quark matter (SQM) composed of up (u), down (d) and strange (s) quarks could be true ground state of strongly interacting matter at high density. Conversion of nuclear matter into SQM via weak interactions give birth to new possibilities of compact objects one is hybrid star and other is strange star. Hybrid star is a NS with core composed of quark matter and SS is entirely composed of SQM up to surface. Recent gravitational waves and NICER observations of pulsars provides us lot of information about constraints on mass, radius and tidal deformability of these compact objects. We model the SQM inside SS to make it compatible with these astrophysical observations. For that we consider modified bag model and vector bag model as stable SQM region can be generated with these two models with certain values of parameters. |
