Aims |
|
|
To build upon the students' knowledge of stellar evolution and describe techniques currently employed to investigate the evolution of stellar populations in the universe. To provide the physical background underlying these techniques, and study their application to observations of Galactic and extra galactic stellar systems. |
|
Learning Outcomes |
|
|
(LO1) An understanding of the evolution with age and chemical composition of the Colour-Magnitude-Diagrams of resolved stellar populations. |
|
|
(LO2) Methods to estimate distances, ages and initial chemical compostions of resolved stellar populations. |
|
|
(LO3) An understanding of the evolution with age and chemical composition of the integrated photometric properties of stellar populations. |
|
|
(LO4) An understanding of the evolution of integrated spectral features of stellar populations with age and chemical composition. |
|
|
(LO5) Knowledge of age and chemical composition diagnostics from integrated photometry and spectroscopy of stellar populations. |

Syllabus |
|
|
From stellar evolution models to observations. Stellar spectra, bolometric corrections, colour magnitude diagrams. Basics of Asteroseismology Concept of simple and composite resolved stellar populations, theoretical isochrones, age/distance diagnostics for simple stellar populations, star formation history determinations for composite stellar populations. Unresolved stellar populations, population synthesis methods, theoretical predictions of integrated spectra and magnitudes of unresolved stellar populations. Age-metallicity degeneracy. Age/metallicity diagnostics based on integrated spectra and integrated magnitudes, stellar mass-to-light ratio estimates. |
