摘要

The equation of state (EOS) of cold and dense strongly interacting matter is crucial for better research of compact stars,i.e.,neutron stars and quark stars.We generalize our improved quasi-particle model from finite temperature and zero chemical potential [Phys.Lett.B 711 (2012) 65] to the case of zero temperature and finite chemical potential to obtain an EOS of our improved quasi-particle model and then apply this EOS to study the structure of a quark star.The results are consistent with the most recent astronomical observational data.
