A study of wormhole solution using MIT bag parameter B in the framework of f(R,Lm,T) gravity
In this study, we explore the existence of traversable wormholes supported by strange quark matter, modeled using the MIT bag equation of state, within the framework of gravity. We analyze wormhole solutions considering three distinct functional forms of the model and adopting two specific shape functions with a logarithmic redshift function. The energy conditions at the throat of the wormhole, located at radius , are examined to assess the influence of the parameters , and on the violations of the energy conditions, particularly the null energy condition. Furthermore, a stability analysis was performed using the Tolman–Oppenheimer–Volkoff (TOV) equation, which confirmed the stability of the obtained wormhole solutions. Lastly, we investigate the active gravitational mass of the wormhole to gain further insight into its physical viability. We have concluded that our wormhole solutions are stable and traversable, with NEC violation due to modified gravity. Despite exotic matter, the wormhole maintains a positive active mass, resembling the gravitational influence of ordinary matter. Our findings contribute to the broader understanding of wormhole solutions in extended theories of gravity and their astrophysical implications.
