Jean instability, mass, radius. Initial mass function (IMF, luminosity function). Chemical evolution (closed-box model, G- dwarf problem, accreting model). Gas in galaxies (HI shells, kinematic distance). Distribution of particles in potential field (thick, thin disk, Toomre’s criterion). Dynamical friction, Chandrasekhar formula. Rotation curves, dark matter. Distance indicators (SN 1987A, cepheids, SN Ia, Hubble’s law). Complementary exercise to the course “Galactic and extragalactic astronomy”.

Syllabus -

Measuring of the distance in the galactic and extragalactic distances (cepheids, SN 1987A, SN Ia, Hubble’s law,…) – comparison and usage. Jeans instability, mass, radius. Comparison of different derivations. Initial mass function, OB associations, luminosity function. Gas in the Galaxy, HI shells, kinematic distance. Rotation curves of galaxies. Dark matter. Classification of galaxies. Chemical evolution of galaxies, instantaneous recycling approximation, G-dwarf problem. Distribution of particles in potential field – thick and thin disk, Toomre’s criterion. Dynamical friction, relaxation time.

Complementary exercise to the course “Galactic and extragalactic astronomy”.
