Abstract

Abstract In this work, we describe the physical features associated with not-static hyperbolically symmetric, dissipative matter configurations by imposing linear f ( T ) corrections, where T is identified as torsion scalar. We show that the coupling of quasi-homologous conditions with minimal gravitational complexity allows us to develop dissipative and non-dissipative hyperbolic stellar configurations with linear torsion corrections. Several explicit models satisfying the above-mentioned conditions are presented. The analysis reveals that negative matter density is an inherent property of the hyperbolically symmetric stellar solution. This unavoidable negativity in energy density indicates that any potential application of such stellar models would be restricted to extreme physical regimes where quantum-scale interactions become significant. This study successfully examines the combined effects of the aforementioned conditions on the dynamic evolution of hyperbolic anisotropic stars with unequal principal stresses.
