Radial Oscillations and Stability of Neutron Stars with Antikaon Condensates
Manisha Kumari, Sujan Kumar Roy, Soumen Podder +2
Radial oscillations provide a direct probe of the stability and compressibility of neutron stars and are highly sensitive to the equation of state of dense matter. In this work, we…

Equation-of-State Independent Relations in Rapidly Rotating Hybrid Stars
Sujan Kumar Roy
We study 22 hadronic and 100 hybrid equations of state (EoSs) that allow for heavy baryons and deconfined quark matter at high densities, aiming to establish quasi-universal relati…

I-C-Q relations for rapidly rotating stable hybrid stars
Sujan Kumar Roy, Gargi Chaudhuri
A number of hadronic equations of state for neutron stars have been investigated for the purpose of the present paper, considering the fact that at sufficiently high density, heavy…
