Abstract: 

A long-standing, open problem in astrophysics, nuclear physics and particle physics is the equation of state (EOS) of dense matter. It is an exciting scientific issue in the physics of compact stars and in the observations at NICER, eXTP, HIAF, etc. Formerly the understanding of this issue relies on electromagnetic observations and heavy-ion experiments, multimessenger observations of neutron star mergers help advance this field of research. Constraints on EOS mainly come from theoretical many-body calculations, laboratory measurements of nuclear properties & reactions and observations in astronomy. I will give a short introduction on the calculations of EOS as well as present constraints.
