Description:
COURSE GOALS:
The principal aim of the course is to give students an introduction into the physics of stars and galaxies, with basics of the observational cosmology and Big Bang theory.

LEARNING OUTCOMES AT THE LEVEL OF THE PROGRAMME:

1.KNOWLEDGE AND UNDERSTANDING
1.1.demonstrate a thorough knowledge and understanding of the fundamental laws of classical
and modern physics;
1.2.demonstrate a thorough knowledge and understanding of the most important physics theories
(logical and mathematical structure, experimental support, described physical phenomena);
2.APPLYING KNOWLEDGE AND UNDERSTANDING
2.1.identify and describe important aspects of a particular physical phenomenon or problem;
2.2.recognize and follow the logic of arguments, evaluate the adequacy of arguments and
construct well supported arguments;
2.3.use mathematical methods to solve standard physics problems;
3.MAKING JUDGEMENTS
3.1.develop a critical scientific attitude towards research in general, and in particular by
learning to critically evaluate arguments, assumptions, abstract concepts and data;
4.COMMUNICATION SKILLS
4.2.present complex ideas clearly and concisely;
5.LEARNING SKILLS
5.2.search for and use professional literature as well as any other sources of relevant
information;
5.3.remain informed of new developments and methods in physics and education;
5.4.develop a personal sense of responsibility for their professional advancement and
development;

LEARNING OUTCOMES SPECIFIC FOR THE COURSE:

By the end of the course, the student should be able to:
1. Describe fundamental astrophysical quantities and link them to stellar spectral
classification;
2. Understand a role of stellar mass and radius with a set of differential equations
of the stellar structure
3. Qualitatively describe radiative transfer in stars and role of convection;
4. Qualitatively describe thermonuclear process in stellar interiors and origin of
the elements
5. Understand and describe stellar evolution and different evolutionary phases (the main
sequence, red giants, white dwarfs, supernovae and neutron stars, and black holes);
explain importance and role of the Hertzsprung-Russel diagram
6. Describe structure of Milky Way, its rotation and kinematics of stars and role of
dark matter; qualitatively describe interstellar matter (gas and dust);
7. Clasify galaxies and describe their main properties;
8. Understand role of the cluster of galaxies and the effect of gravitational lensing;
9. Describe the main issues of the observational cosmology and understand fundamental
observational findings (expansion of the Universe and Hubble law, background radiation,
outcomes of the primordial nucleosynthesis and the origin of elements);
10. Describe fundaments of the Big Bang theory and problem of dark matter and dark
energy in the Universe
