ECTS credit allocation (and other scores): (not available) Basic information on ECTS credits allocation principles:
  • the annual hourly workload of the student’s work required to achieve the expected learning outcomes for a given stage is 1500-1800h, corresponding to 60 ECTS;
  • the student’s weekly hourly workload is 45 h;
  • 1 ECTS point corresponds to 25-30 hours of student work needed to achieve the assumed learning outcomes;
  • weekly student workload necessary to achieve the assumed learning outcomes allows to obtain 1.5 ECTS;
  • work required to pass the course, which has been assigned 3 ECTS, constitutes 10% of the semester student load.

Short description:

An aim of the lecture and the colloquium seminars is to acquaint students with chosen subjects of modern astrophysics and cosmology. The classes should be given in a classroom with blackboard. The classes will also be illustrated by diagrams, figures, photos or movies.

Full description:

Subjects realized at the lecture:

I. Structure of stars, evolution of stars:

1. The virial theorem. The negative specific heat of a star. The thermal, the dynamic, and the nuclear time-scales.

2. The Planck function, Wien and Rayleigh-Jeans formulas, Wien's displacement law.

3. Hydrostatic equilibrium in the stars.

4. Nuclear fusion in the stars: Coulomb barrier, proton-proton chain reaction, CNO cycle and triple-alpha process.

5. Energy transport in the star: convective heat transfer, radiative transport, conductivity.

6. Star formation: Jeans mass.

7. Planetary nebula, nova & supenova.

8. Binary stars: the Lagrangian points. the Algol paradox, the Eddington luminosity.

II. Relativistic astrophysics:

1. The Pauli exclusion principle, equation of states of degenerated matter.

2. White dwarf: basic parameters, Chandrasekhar limit.

3. Neutron star and pulsar: basic parameters, structure, the lighthouse model.

4. Black hole: event horizon, relativistic properties, Hawking radiation. Black holes in our Universe.

5. Gravitational waves: properties, detectors. Hulse–Taylor binary, the source GW150914, GW170817.

III. Cosmology:

1. The Big Bang Theory

2. The Standard Model (Friedmann–Lemaître–Robertson–Walker universe).
