Course Content
The course examines the modern theory of stellar structure and evolution, with emphasis on the physical mechanisms that determine the internal structure of stars and their evolution beyond the classical single‑star approach. Particular emphasis is placed on the role of rotation, angular‑momentum transport, and chemical mixing, as well as on the effects of stellar multiplicity (binary and multiple systems) on stellar evolution and end stages. The fundamental principles of thermonuclear burning and nucleosynthesis are presented, both in quiescent evolutionary phases and in explosive phenomena such as supernovae and compact‑object mergers (kilonovae). The course connects theoretical models with observational constraints and with the chemical evolution of galaxies, and is taught with a “learning by research” philosophy through the study and discussion of contemporary research articles, preparing students for research activity in theoretical, observational, or computational astrophysics.
