Basics of radiative transfer; the measurement of star physical parameters; stellar structure; stellar evolution; binary systems and accreyion; interstellar medium and star formation; fluidodynamics of atsrophysical processes; galaxies: morphological and dynamical properties, the Milky Way, dark matter; Active Galactic Nuclei and supermassive black holes; galaxy clusters; introduction to Cosmology.
Skills acquired (at the end of the course):
At the end of the course the student will have a broad knowledge of astrophysical objects and of the main physical processes, especially in relation with stars, galaxies, active nuclei and galaxy clusters. Moreover, the student will have acquired a basic knowledge of the standard cosmological model.
