Résumé : In core-collapse events matter is heated and compressed to densities above nuclear matter saturation density. For progenitors with massesabove about 25 solar masses, which eventually form a black hole, the temperatures and densities reached during the collapse are so highthat a traditional description in terms of electrons, nuclei, and nucleons is no longer adequate. We will present here an improved equation of state which contains in addition pions and hyperons. They become abundant in the high temperature and density regime, and we will discuss the effect on the thermodynamic properties.
