The group "Hadron Physics and Nuclear Astrophysics" is involved in the following research lines:1. The study of the behaviour of nuclear matter at high densities considering the hadron and quark phases at zero temperature. 2. The study of neutron stars cooling through neutrino emission in the direct URCA process. 3. The implications of an isovector light scalar partner of the sigma meson in dense nuclear matter.4. The study of phase transitions from hadron matter to deconfined quark matter.5. The study of properties of strange quark matter and strange stars.6. The description of the Okamoto-Nolen-Schiffer anomaly in nuclear physics.7. The study of properties of medium and large mass nuclei.
