Compact stars in gravity

JC de Araujo, HGM Fortes - arxiv preprint arxiv:2407.08884, 2024‏ - arxiv.org
General Relativity (GR) is not the only way gravity can be geometrised. Instead of curvature,
the Teleparallel Theory attributes gravity to torsion $ T $, which is related to the …

Two novel models
