Surface Enhanced Anisotropy and Its Impacts on Massive Neutron Star Configurations in Einstein Gravity : Stability, Structure, and Multimessenger Consistency

Ritabrata Biswas, Arpan Bhattacharya, Subhajit Pal

Anisotropic neutron-star configurations are investigated within Einstein's General Relativity using a third-order polynomial equation of state, (p_r=Aρ+Bρ^2+Cρ^3), and the Buchdahl…
