Quark star quark stars. It has been suggested that the collapsed core of supernova SN 1987A may be a quark star. In 2015, Z.G. Dai et al. from Nanjing University suggested that Supernova ASASSN-15lh is a newborn strange quark star. Apart from ordinary quark matter and strange quark matter, other types of quark-gluon plasma might theoretically occur or be formed inside neutron stars and quark stars. This includes the following, some of which has been observed and studied in laboratories: Quark star A quark star is a hypothetical type of compact exotic star, where extremely high temperature and pressure has forced nuclear
