Abstract

This work investigates the properties of spin polarized strange quark matter SQM and the resulting structure of strange quark stars SQSs within a thermodynamically self consistent quasiparticle framework. By developing a dynamic bag constant intrinsically coupled to the medium dependent reduction of quark effective masses we ensure strict internal thermodynamic consistency. This coupling gives rise to a distinct non monotonic behavior in the speed of sound significantly stiffening the Equation of State EoS at high densities. Consequently our model predicts maximum stable gravitational masses up to 2.19 Mo. These results demonstrate that hot magnetized SQM provides a robust and viable mechanism to explain ultra massive pulsars such as PSR J0740 6620 and PSR J0952 0607 without requiring unrealistic thermal or structural assumptions.
