Density-induced dark-baryon conversion in admixed hypernuclear neutron stars
Niyar Prabhat Kalita, Vivek Baruah Thapa, Bhanu Prakash Pant +2
We investigate density-induced conversion of neutrons into a neutral dark baryon in cold, charge-neutral, -equilibrated neutron-star matter containing hyperons and all $Δ(12…
A Theoretical Study of the Structure and Elemental Abundances of HD 20794
Mrinmay Medhi, Mami Deka, Krishna Saha +2
HD~20794 is a nearby, bright, metal-poor G-type dwarf hosting a compact planetary system, including a super-Earth near the habitable zone. Its low stellar activity and the availabi…
Dense Matter and Compact Stars in Strong Magnetic Fields
Monika Sinha, Vivek Baruah Thapa
Compact stars serve as natural systems where matter exists at densities far beyond those achievable in laboratory experiments. Among them, magnetars are expected to possess interio…
Kaon-meson coupling from SU(3) flavour symmetry and application to antikaon condensed dense matter in neutron star
Athira S., Monika Sinha, Vivek Baruah Thapa +1
Observations of massive pulsars suggest that the central density of neutron stars can exceed several times the nuclear saturation density, creating a favourable environment for the…
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 relat…
Bayesian Inference of dense matter equation of state of neutron star with antikaon condensation
Vishal Parmar, Vivek Baruah Thapa, Anil Kumar +2
In this paper, we employ the Density Dependent Relativistic Hadron (DDRH) field theoretical Model in a Bayesian analysis to investigate the equation of state (EOS) of dense matter…
Exploring non-radial oscillation modes in dark matter admixed neutron stars
Pratik Thakur, Anil Kumar, Vivek Baruah Thapa +2
Because of their extreme densities and consequently, gravitational potential, compact objects such as neutron stars can prove to be excellent captors of dark matter particles. Cons…
Universal relations for compact stars with exotic degrees of freedom
Anil Kumar, Manoj Kumar Ghosh, Pratik Thakur +2
The nature of the highly dense matter inside the supernova remnant compact star is not constrained by terrestrial experiments and hence modeled phenomenologically to accommodate th…
Fast neutron star cooling in light of the PREX-2 experiment
Trisha Sarkar, Vivek Baruah Thapa, Monika Sinha
The nuclear symmetry energy and its behaviour with density has been recently evaluated with enhanced value by PREX-2 experiment. This new values enables direct Urca neutrino emissi…
Hybrid stars are compatible with recent astrophysical observations
Anil Kumar, Vivek Baruah Thapa, Monika Sinha
Compact stars (CS) are stellar remnants of massive stars. Inside CSs the density is so high that matter is in subatomic form composed of nucleons. With increase of density of matte…
Tension between implications from PREX-2 data and gravitational tidal response on dense matter equation of state
Vivek Baruah Thapa, Monika Sinha
Recently an improved value of neutron skin thickness of was reported in Lead Radius EXperiment-2 (PREX-2) to be fm wh…

Vivek Baruah Thapa, Mikhail V. Beznogov, Adriana R. Raduta +1
A large collection of equations of state (EOSs) built within the covariant density functional (CDF) theory of hadronic matter and allowing for density dependent (DD) couplings is e…
(Anti)kaon condensation in strongly magnetized dense matter
Debraj Kundu, Vivek Baruah Thapa, Monika Sinha
Recent observations of several massive pulsars, with masses near and above , point towards the existence of matter at very high densities, compared to normal matter that…

The detection of gravitational waves from the merger of binary neutron stars events (GW170817, GW190425) and subsequent estimations of tidal deformability play a key role in constr…
