stellar population - rendering tools
Lecturer: L. Greggio

The course aims at illustrating theoretical concepts at the basis of the interpretation of the properties of galaxies, viewed as
collections of stellar generations.

1. Brief summary of the stellar evolution theory, with emphasis on the features of stellar tracks mostly relevant for the appearence of the HR diagram. Dependence on age and metallicity of these features. (2 hours).

2. From the theoretical to the observational plane: bolometric corrections and colours; photometric systems; model atmospheres; spectral libraries. (2 hours).

3. Star counts on the CMD: fundamental relations (stellar evolutionary flux, evolutionary lifetimes, specific production of stars in different evolutionary phases). Application of these concepts to Simple and Composite Stellar Populations. (2 hours).

4. Reconstruction of the Star Formation History of a stellar system from the analysis of its Colour-Magnitude Diagram: current methods and one example from the literature. (2 hours).

5. Simple Stellar Populations (SSPs) in integrated light: isochrones, Fuel Consumption Theorem. Luminosity and Colour
Evolution. Evolution of the Spectral Energy Distribution. Dependence on metallicity. (2 hours).

6. Spectrophotometric Indices, age-dating and metallicity determination of stellar systems from their integrated light. M/L
ratios of SSPs. (2 hours).

7. Composite Stellar Populations: SED of galaxies, redshift evolution, photometric redshifts. (2 hours).

8. The drop-outs technique, Lyman Break galaxies, BZK galaxies. One example of this kind of studies from the literature. (2 hours).
