## Module content and teaching

###### Principal aims

The module introduces fundamental astronomical concepts such as how to measure their distances, brightness and colour, and illustrates the extreme variety of stars found in our Galaxy. It is shown how fundamental concepts of physics are used to quantitatively describe the structure and evolution of stars. The module also conveys how observational methods such as imaging and spectroscopy are used to test our understanding of the origin, life, and death of stars.

###### Principal learning outcomes

At the end of the module, you should be able: to define the position of a star; to describe the techniques used to determine their distance from us; to relate basic quantities such as apparent magnitude, absolute magnitude, flux, luminosity, stellar radius, effective temperature and distance; to explain the main characteristics of stellar spectra along the main sequence; to understand the basic mechanisms of interaction between photons and matter occurring in the atmosphere of a star; to understand the basic physical principles necessary to describe the structure and evolution of stars, and to qualitatively describe the birth, life and death of stars; to be able to describe the processes of nuclear fusion that powers the light of almost all stars; to identify the main features of the Hertzsprung-Russell diagram.
