Query: The induced surface tension contribution for the equation of state of
  neutron stars   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 constraints, hadron multiplicities
created during the nuclear-nuclear collision experiments, and equally is
consistent with astrophysical data coming from NS observations. The analysis
suggests that the best model parameterization gives the incompressibility
factor $K_{0}$, symmetry energy $J$, and symmetry energy slope $L$ at normal
nuclear density equal to $200$ MeV, $30$ MeV, and $113.28-114.91$ MeV,
respectively. The mass-radius relations found for NSs computed with this EoS
are consistent with astrophysical observations.
