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 rela…
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…
