| Abstract: | It is well known that the matter at supra-nuclear densities can undergo a phase transition from ordinary state, made mostly of neutrons and protons to pure quark matter. Thus neutron stars can contain a quark core and in this case they must be referred to as "hybrid" star which are between ordinary neutron stars and hypothetical quark stars. The problem of hybrid stars is directly connected to two main topics of modern astrophysics: first the EOS of high-density matter in connection with the maximum neutron star mass. And second – the problem of core-collapse supernovae in light of new phase-transition induced model of explosion, developed by Basel group. Beside this, the hybrid stars itself have a lot of unusual and interesting properties, few of which will be described in this talk also. |
