A.4. Stellar nucleosynthesis

A.5. Explosive nucleosynthesis

B.1. Equation of state of an ideal gas: electrons and photons

B.2. Phenomenological models of nuclear matter: Skyrme interactions

B.3. Equation of state of symmetric, asymmetric and -stable matter

C.1. Astroparticle physics and nuclei: direct detection of dark matter

C.2. White dwarfs: mass and size

C.3. Neutron stars: general characteristics

C.4. Neutron stars: crust and cooling

C.5. Neutron star mergers: gravitational waves

D.1. Numerical applications (I): nuclear equation of state

The lectures of the first week will take place online. The lectures of the second week will be given in the classroom at the Faculty of Physics of the University of Barcelona.

Examination: the examination will be based on the solution of a few proposed exercises, which should be handed in by the student before May 26, 2023.
