The ARPIT 2020 course on Astronomy and Astrophysics is titled “Stars and stellar systems”. An understanding of this field, which draws upon our knowledge of different branches of physics, is fundamental to our understanding of the universe. The course is made up of 10 modules addressing different aspects of the field: Stars and stellar evolution; Stellar variability; Stars and cosmology; Star clusters and star formation; Compact stars; Astrophysics of neutron stars; Binary stellar systems; The Sun; Helio- and astero-seismology; Extrasolar planets. Besides refreshing oneself on the basics and recent developments in the field, the material would also be helpful for teachers of physics wishing to learn the subject to teach.
