Syllabus
Prerequisites: Fundamentals of stellar astrophysics (photometry, astrometry, spectroscopy, stellar evolution)
Target skills and knowledge: The student will deal with the main properties of stellar populations in the Solar neighbours, in star clusters, in the Milky Way and in galaxies.
S/he will learn how to interpret the observations of stellar populations and use them to shed light on the main issues of modern stellar astrophysics and cosmology.
Examination methods: Oral exam based on the topics discussed during the lectures.
Assessment criteria: Knowledge of the program, capability to present the different topics of the program with a scientifically appropriate language, critical approach to the comparison between theory and observations.
Course unit contents: 1) Color-magnitude diagrams: transformation luminosity-magnitude and color-temperature, bolometric corrections, effect of reddening, metallicity and chemical composition.
2) Definition of stellar population. historical background, present-day view. Stellar clusters as prototype of simple populations. The initial mass function.
3) Determination of the physics and structure parameters of stellar population from photometry (age, reddening, metallicity).
4) Chemical composition of stellar populations.
5) Binaries, Blue Stragglers, X-ray Binaries, black holes and other exotic objects in star clusters.
6) Population III stars. Hunting the first stars of the Universe.
7) The Galactic halo
- Ultra faint dwarfs
- Dwarf galaxies
- Globular clusters. Multiple stellar populations. Horizontal branch and second-parameter problem.
8) Galactic Bulge.
9) Thin and thick disk.
Open clusters. Multiple stellar populations in Magellanic Clouds clusters and the eMSTO phenomenon. Solar neighbours.
10) Star formation history in dwarf galaxies and in the Milky Way.
Planned learning activities and teaching methods: Lectures in classroom. Discussion on the major literature papers and new results on stellar populations.
Additional notes about suggested reading: Lecture notes available through the website of the course on the e-learning platform of the Department of Physics and Astronomy "G. Galilei" (https://elearning.unipd.it/dfa/).
