Axion-angle dependence of the rotational and tidal properties of PNJL quark stars
Safiqul Islam, Ayan Banerjee, Javlon Rayimbaev +1
We investigate how a fixed, spatially uniform axion angle modifies the rotational and static tidal properties of self-bound quark stars in general relativity, using an axion-extend…
Quark stars in regularized 4D Einstein-Gauss-Bonnet gravity: A perturbative QCD equation of state
Anirudh Pradhan, Safiqul Islam, Safyan Mukhtar +1
We investigate the equilibrium structure and stability of selfbound quark stars in the framework of regularized four-dimensional Einstein--Gauss--Bonnet (4DEGB) gravity, employing…
Traversable wormholes in gravity: a complete classification of the non-exotic sector
Ayan Banerjee, Takol Tangphati, Safiqul Islam +1
We study static and spherically symmetric traversable wormholes in gravity, where the torsion scalar is coupled to the trace of the matter energy--momentum tensor.…
Neutron Stars in Energy--Momentum Squared Gravity: Structure, Stability, and Multimessenger Constraints
Baiju Dayanandan, Anirudh Pradhan, Safiqul Islam +1
We study nonrotating neutron stars in energy--momentum squared gravity (EMSG). The stellar models are obtained from the modified Tolman--Oppenheimer--Volkoff equations and four ori…
