摘要：

The high-density nuclear equation of state within the Brueckner-Hartree-Fock approach is discussed. Particular attention is paid to the effects of nucleonic three-body forces, the presence of hyperons, the joining with an eventual quark matter phase, and the extension to finite temperature. The resulting properties of neutron stars, in particular the mass-radius relation, are determined. It turns out that in this approach stars heavier than about 1.4 solar masses contain necessarily quark matter.
