Fermionic versus Bosonic Dark Matter in Neutron Stars: A Bayesian Study with Multi-Density Constraints
Payaswinee Arvikar, Sakshi Gautam, Anagh Venneti +1
We perform a comparative Bayesian analysis of fermionic and bosonic dark matter admixed neutron stars (DMANS) by incorporating a comprehensive set of theoretical, experimental, and…

Systematic study of scalar, vector, and mixed density dependencies in relativistic mean-field descriptions of hyperonic matter in neutron stars
Aprajita Shrivastava, Prasanta Char, Sakshi Gautam +1
We investigate the equation of state (EOS) of hyperonic neutron star (NS) matter within a density-dependent relativistic mean-field (DDRMF) framework. The effects of scalar, vector…

Exploring Fermionic Dark Matter Admixed Neutron Stars in the Light of Astrophysical Observations
Payaswinee Arvikar, Sakshi Gautam, Anagh Venneti +1
We studied the properties of dark matter admixed-neutron stars (DMANS), considering fermionic dark matter (DM) that interacts gravitationally with hadronic matter (HM). Using relat…
