Learning outcomes
The aim of this course is to obtain a general understanding of physical properties of stars and galaxies. At the end of the lectures the student will know the equations that regulate the internal structure of the stars, the sources of energy production, the structure of stellar atmosphere and the formation theory of the spectral lines. The student will acquire a general knowledge of morphological, structural and dynamical properties of stellar systems (stellar clusters, galaxies, ...). Hence, he/she will acquire the necessary bases to understand the structural and evolutionary properties of stars and galaxies.
Course contents
Structure of stars. Equations of stellar interiors. The physical state of stellar matter. Thermonuclear reactions. Energy transport. The opacity in the stellar interiors. The Schwarzshild criterium. Stellar atmospheres. Basic stellar evolution. Observational and kinematical properties of stellar systems, from galactic to cluster scales. Introduction to observational Cosmology.
