Syllabus
Prerequisites: The course assumes that the students well know general physics (thermodynamics, fluid dynamics, electromagnetism) and basics of atomic physics.
Target skills and knowledge: The course will give the theoretical and practical instruments to approach the physical study of the magneto-hydrodynamical and radiative processes present in the interstellar medium.
Examination methods: Oral exam possibly integrated by the presentation of a topic related to the program agreed in advance with the teacher.
Assessment criteria: Knowledge of the program, ability to express the physical concepts about the interstellar medium in a proper way, capability to extract the physical information from the spectra of gaseous nebulae.
Course unit contents: 1) Introduction.
2) Equations of hydro-dynamics, turbulence, thermal balance in the interstellar medium.
3) Shock waves, Riemann problem
4) Magneto-hydrodynamics, Alfven waves, Galactic magnetic field; generalized virial theorem; ambipolar diffusion
5) Numerical techniques for the solution of the magneto-hydrodynamic equations (Eulerian vs Lagrangian approaches).
6) General picture of the interstellar medium: HI, CO, H2, molecules.
7) Theories of star formation, Jeans criterion, sequential star formation.
8) HII regions, Stroemgren sphere.
9) Effects on the interstellar medium of stellar winds and supernovae remnants
10) Chemical enrichment of the interstellar medium: basic equations
Planned learning activities and teaching methods: Lectures and exercises on observational data. Lectures are given in Italian.
Additional notes about suggested reading: Textbooks and lecture notes written by the teacher available through the Moodle website of the course on the e-learning platform of the Department of Physics and Astronomy "G. Galilei" (https://elearning.unipd.it/dfa/).
