$K^{-}$ -Driven Direct Urca Cooling in Rotating Neutron Stars: A Bayesian Study

Aprajita Shrivastava, Debanjan Guha Roy, Sarmistha Banik

We investigate the onset of antikaon ( $K^{-}$ ) condensation and its implications for the equation of state (EoS) and cooling of neutron stars (NSs) within density-dependent relativis…

Signatures of $K^{-}$ condensation on neutron star structure and $f -$ mode frequencies

Debanjan Guha Roy, Sarmistha Banik

Antikaon ( $K^{-}$ ) condensation within neutron star matter (NS) depends on the antikaon-nucleon interaction potential ( $U_{K}$ ). Appearance of $K^{-}$ generally softens the equation of s…

Analysis of Neutron Star $f -$ mode Oscillations in General Relativity with Spectral Representation of Nuclear Equations of State

Debanjan Guha Roy, Tuhin Malik, Swastik Bhattacharya +1

We study quasinormal $f -$ mode oscillations in neutron star(NS) interiors within the linearized General Relativistic formalism. We utilize approximately 9000 nuclear Equations of St…
