Influence of chemical potential to explain the maximum mass and tidal love number of strange stars
Abstract
We investigate the influence of medium effects on strange quark matter and their consequences for the structural properties of compact stars. In this study, the bag constant, in the MIT bag model equation of state, is reformulated as a function of the chemical potential of quark. Imposing the Bodmer-Witten stability criterion, the parameter space is constrained by evaluating the energy per baryon. The Tolman-Oppenheimer-Volkoff equations are then solved to obtain the maximum mass-radius configurations. Our analysis shows that an increase in chemical potential leads to a reduction in the effective value of bag constant, resulting in a stiffer equation of state and correspondingly higher value of maximum stellar mass. Furthermore, we examine the chemical potential dependence of the tidal Love number and tidal deformability along with their corresponding finite surface density corrections. The results demonstrate that, for the chosen set of parameters, the constraint from the GW170817 event, namely Λ< 800, is consistently satisfied. In this paper, we have tried to establish how chemical potential (μ) affects the maximum mass and tidal deformability of strange stars.
