Model of hybrid star with baryonic and strange quark matter in Tolman–Kuchowicz spacetime

The purpose of our work is to investigate some new features a static anisotropic relativistic hybrid compact star composed strange quark matter (SQM) in the inner core and normal baryonic distribution crust. Here we apply simplest form phenomenological MIT bag model equation state [Formula: see text] correlate density pressure within stellar interior, whereas radial due are connected by simple linear text]. In order obtain solution Einstein field equations, have used Tolman–Kuchowicz ansatz [R. C. Tolman, Static solutions Einstein’s equations for spheres fluid, Phys. Rev. 55 (1939) 364–373; B. Kuchowicz, Acta Pol. 33 (1968) 541] further derivation arbitrary constants from physical conditions. Here, examine proposed graphically analytically detail physically plausible particular, this investigation, reported on object Her [[Formula: text]; km] paper as candidate. check validity stability suggested model, performed various tests both graphically, namely, dynamical equilibrium applied forces, energy conditions, compactness factor surface redshift. Finally, found that present meets all necessary requirements realistic can be studied stars (SQS).
