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…
