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 …
