Neutron star matter with hyperons: Bayesian comparison of nucleonic and SU(6)/SU(3) hyperonic models
Athira S., Vishal Parmar, Monika Sinha +1
We investigate neutron star matter with hyperons within a density-dependent relativistic mean-field framework using Bayesian inference, considering three composition scenarios: pur…
Nuclear Pasta and Crustal Quasi-Periodic Oscillations in Neutron Star
Vishal Parmar, Ignazio Bombaci
We investigate the impact of nuclear pasta on crustal structure and torsional oscillations using a Bayesian ensemble of unified neutron-star equations of state based on relativisti…
Multi-Physics Bayesian Analysis of Neutron Star Crust Using Relativistic Mean-Field Model
Vishal Parmar, Ignazio Bombaci
We study the properties of neutron-star crust within a Bayesian framework based on a unified relativistic mean-field (RMF) description of dense matter. The analysis focuses on the…
Triggering Electron Capture Supernovae: Dark Matter Effects in Degenerate White-Dwarf-like Cores of Super-Asymptotic Giant Branch Stars
Vishal Parmar, Domenico Scordino, Ignazio Bombaci
Electron-capture supernovae (ECSNe) have emerged as a compelling formation channel for low-mass neutron stars, bolstered by decades of theoretical work and increasingly supported b…
Exploring -resonance in neutron stars: implications from astrophysical and nuclear observations
Vishal Parmar, Vivek Baruah Thapa, Monika Sinha +1
This study presents the first comprehensive Bayesian inference of neutron star matter, incorporating -resonances alongside hyperons and nucleons within a density-dependent rela…
Dark matter admixed neutron stars with a realistic nuclear equation of state from chiral nuclear interactions
Domenico Scordino, Ignazio Bombaci
We study the effects of dark matter on the structural properties of neutron stars. In particular we investigate how the presence of a dark matter component influences the mass-radi…
