Learning outcomes

After completing the course the student should have understanding of: spectral line formation; heating and cooling in diffuse media; formation and destruction of molecules and dust grains in diffuse media; the roles of dust in the interstellar medium; ionised regions around hot stars and their evolution; gas dynamics and astrophysical shocks; stellar winds and supernovae and their effects on their environments; structure of the interstellar medium; processes in star forming regions


- Observations of interstellar medium (ISM): spectal lines, continuum radiation, extinction
- Microscopic processes in the ISM: cooling and heating of interstellar gas, molecule formation
- Interstellar dust grains: Observations, formation and destruction and physical properties
- Radiatively excited regions: Observations and physical structure of nebulae
- Introduction to gas dynamics: Basic equations from conservation laws, sound waves, shocks
- Gas dynamical effects of massive stars on the ISM: Expansion of Nebulae, stellar winds, supernovae and supernova remnants, groups of massive stars
- Star formation and star forming regions
