Reaction-constrained composition \(g\)-modes in neutron stars with antikaon condensates, hyperons, and \(Î(1232)\) resonances
Prashant Thakur, Ishfaq Ahmad Rather
We study core composition \(g_1\) modes of cold, nonrotating neutron stars containing antikaon condensates, hyperons, and \(Î(1232)\) baryons and present, to our knowledge, the fi…
Amortized Simulation-Based Inference of Relativistic Mean-Field Couplings for Neutron-Star Equations of State
Prashant Thakur, Tuhin Malik
We present a simulation-based inference framework for constraining microscopic relativistic mean-field parameters of neutron-star equations of state. Neural posterior estimation is…
Rotational enhancement and stability of protoquark stars during thermal evolution
Adamu Issifu, Andreas Konstantinou, Prashant Thakur +1
We present the first systematic study of rigidly rotating protoquark stars based on isentropic equations of state (EOS) within the density-dependent quark mass (DDQM) framework. Us…
Dark Matter Heating in Evolving Proto-Neutron Stars: A Two-Fluid Approach
Adamu Issifu, Prashant Thakur, Davood Rafiei Karkevandi +4
Neutron stars (NSs) provide a unique laboratory to probe dark matter (DM) through its gravitational imprint on stellar evolution. We use a two-fluid framework with non-annihilating…
Probing Strange Dark Matter through -mode Oscillations of Neutron Stars with Hyperons and Quark Matter
Mahboubeh Shahrbaf, Prashant Thakur, Davood Rafiei Karkevandi
We investigate the impact of a hypothetical bosonic dark matter (DM) candidate, the sexaquark, on the fundamental (-mode) oscillations of neutron stars (NSs). By varying the DM…
Magnetized Proto-Neutron Stars: Structure and Stability
Harsh Chandrakar, Adamu Issifu, Prashant Thakur +2
We investigate the evolution of magnetized protoneutron stars (PNSs) through four schematic stages: neutrino trapped, deleptonization, neutrino transparent, and the final cold, cat…
