We present the unified equation of state with induced surface tension (IST) that reproduces the nuclear matter properties, fulfills the proton flow constraint, provides a high-quality description of hadron multiplicities created during the nuclear-nuclear collision experiments, and is equally consistent with NS observations. Obtained tidal Love numbers are in full agreement with the constraints deduced from the observations of the binary NS mergers. Moreover, we demonstrate the IST EoS to be consistent with the universality of the I-Love-Q relations. Cooling simulations for isolated neutron star show very good agreement with astrophysical observations.
