Recent multimessenger constraints and the anisotropic neutron star

A Rahmansyah, A Sulaksono - Physical Review C, 2021 - APS
The impact of anisotropic pressure models in neutron stars (NSs) is increasing their
compactness. Therefore, for the relatively soft NS equation of state (EOS), we can still obtain …

We investigate the f-mode oscillation of the dark matter admixed hyperon star within the
relativistic Cowling approximation. The macroscopic properties are calculated with the …

relation for an anisotropic neutron star

HC Das - Physical Review D, 2022 - APS
One of the most common assumptions has been made that the pressure inside the star is
isotropic in nature. However, the pressure is locally anisotropic in nature which is a more …
