Description
In the relativistic mean-field Quark-Meson-Coupling (QMC) model, the baryon-baryon interaction in medium is interpreted in terms of a virtual meson exchange between light valence quarks in individual baryons [1]. This unique feature leads to a dramatic reduction of variable parameters of the model as compared to traditional nuclear structure models, and to a versatile application to high density matter in compact objects as well as to a wide range of properties of finite nuclei [2]. In this presentation, I will focus on the QMC predictions of the Equation of State of cold and hot matter in neutron stars and supernovae [3]. Composition of the matter, including leptons and heavy strange baryons, its density and temperature dependence and its effects on the maximum mass of cold neutron stars, the speed of sound and rotation properties will be discussed.
