# The Induced Surface Tension Contribution for the Equation of State of Neutron Stars

@article{Sagun2019TheIS, title={The Induced Surface Tension Contribution for the Equation of State of Neutron Stars}, author={Violetta Sagun and Il{\'i}dio Lopes and A. I. Ivanytskyi}, journal={The Astrophysical Journal}, year={2019}, volume={871} }

We apply a novel equation of state (EoS) that includes the surface tension contribution induced by interparticle interaction and asymmetry between neutrons and protons, to the study of neutron star (NS) properties. This elaborated EoS is obtained from the virial expansion applied to multicomponent particle mixtures with hard core repulsion. The considered model is in full concordance with all the known properties of normal nuclear matter, provides a high-quality description of the proton flow…
