Physical implications of teleparallel gravity on stellar configurations with modified Van der Waals equation of state: a broader view

The physical properties of spherically symmetric, static, anisotropic compact configurations in the paradigm of Teleparallel gravity are investigated in this paper. To establish bounded stellar configurations, we assume that the interior matter distribution follows the non-linear form of the modified Van der Waals equation of state in combination with the metric ansatz for one of the gravitational potentials. It should be emphasized that the theory’s parameters have been proved to be the main factors of our stellar models’ gravitational and thermodynamic behavior. We showed that the matter variables have higher values at the core and then drop monotonically to attain the lowest values at the boundary, while the radial pressure vanishes at the stellar surface. This obviously demonstrates that the star’s core is highly compact, and our stellar system is valid for the region outside the star’s core. However, the pressure anisotropic function consistently stays positive all through the star with some intriguing physical aspects throughout our findings coming from the theory. In conclusion, the findings suggest that our stellar system is robust and physically viable in modified physical acceptability and also it provides direct evidence in favor of compact static spherically symmetric objects as an alternative to neutron stars, which is a class of compact stars dubbed as strange stars in the context of Teleparallel gravity.
