Bayesian analysis of density profile of light dark matter elucidating the properties of dark matter admixed neutron stars in the presence of hyperons

Debashree Sen, Atanu Guha, Chang Ho Hyun

We study the impact of symmetry energy (), hyperons, and dark matter (DM) on structural and oscillatory properties of neutron stars (NSs). Uncertainty from hadronic equation of…

and mode oscillation of proto-neutron stars with systematic variation of the nucleon effective mass

Atanu Guha, Debashree Sen, Hana Gil +2

We develop equation of state (EoS) of proto-neutron stars (PNSs) at various stages of evolution by varying entropy per baryon , using the Korea-IBS-Daegu-SKKU density functional…

Role of density profile of sub-GeV dark matter in the properties of dark matter admixed quark stars with Bayesian analysis of dark-NJL model

Debashree Sen, Atanu Guha, Jong-Chul Park

We investigate the structural and oscillation properties of dark matter (DM) admixed strange quark stars (DMSQSs). The strange quark matter (SQM) is described with the well-known N…

Non-radial oscillations of hadronic neutron stars, quark stars, and hybrid stars : Calculation of , , and mode frequencies

Atanu Guha, Debashree Sen, Chang Ho Hyun

The composition and equation of state (EoS) of dense matter relevant to compact stars are quite inconclusive. However, certain observational constraints on the structural propertie…

Effects of dark boson mediated feeble interaction between dark matter (DM) and quark matter on -mode oscillation of DM admixed quark stars

O. P. Jyothilakshmi, Lakshmi J. Naik, Debashree Sen +2

We investigate the behavior of the prominent non-radial fundamental -mode oscillations of dark matter (DM) admixed strange quark stars (DMSQSs), by adopting an equation of state…

Influence of the effective mass on the properties of nuclear matter at finite density and temperature

Hajime Togashi, Debashree Sen, Hana Gil +1

Significance of the chiral symmetry restoration is studied by considering the role of the modification of the nucleon mass in nuclear medium at finite density and temperature. Usin…
