Description
This study explores the equations of state for strange quark matter as a superdense ground state within the MIT bag model, considering both fixed and baryon density–dependent parameters. We examine the structure of cold, self-bound strange stars capable of reaching masses above two solar masses, forming a continuous family with neutron stars along the mass–central density (M(ρ_c)) relation. The primary aim is to compare these theoretical mass predictions with recent precise pulsar mass measurements. By solving the Tolman–Oppenheimer–Volkoff equations numerically, we evaluate two scenarios: (1) fixed bag model parameters m_s,α_c,B; (2) fixed m_s,α_c with B=B(n_B). In this discussion, we address the solutions to the equations of state and subsequently examine the relativistic equations governing compact stars, incorporating the non-zero masses of first-generation quarks. Using numerical calculations based on their experimentally determined values with specified accuracy, we analyze the resulting relationships between these parameters and the various physical quantities.
