Compact star merger events with stars composed of interacting strange quark matter

Abstract

We investigate the properties of stars participating in double compact star merger events considering interacting model of stable strange quark matter. We model the matter making it compatible with the recent astrophysical observations of compact star mass-radius and gravitational wave events. In this context we consider modified MIT bag model and vector bag model with and without self interaction. We find new upper bound on tidal deformability of $1.4M_{\odot }$ strange star corresponding to the upper bound of effective tidal deformability inferred from gravitational wave event. Range of compactness of $1.4M_{\odot }$ strange star is obtained as $0.175\le C_{1.4}\le 0.199$. Radius range of $1.5M_{\odot }$ primary star is deduced to be $10.57\le R_{1.5}\le 12.04$ km, following stringent GW170817 constraints. GW190425 constraints provide with upper limit on radius of $1.7$ solar mass strange star that it should be less than $13.41$ $\text{km}$.
