Stars are central objects within astronomy: they are interesting objects in their own right, and they are important components of galaxies whose dynamics and history can be studied through observations of stars. In addition, essentially all of the elements in our universe have their origin inside stars. Stars are complex systems. The theory of stellar structure and evolution rests on many parts of physics: mechanics, hydrodynamics, thermodynamics, statistical physics, the most extreme examples of condensed matter physics, nuclear physics, atomic physics, and radiative transfer and spectroscopy. The course will provide a deep understanding of the workings of stars, and it will provide an excellent example of how applied physics is used to describe a complex phenomenon.Learning outcomes (after completion of the course the student should be able to)
- describe what can be learned about stars and their evolution from observations
- write the equations of stellar structure and explain them
- derive the characteristic timescales of stellar evolution, and the characteristic temperatures, densities, and pressures in stellar interiors
- describe radiative transport in stellar interiors
- describe convection in a star and list the consequences of it for stellar evolution; derive under which conditions a star is convective
- describe stellar atmospheres and how radiative transfer models are used to explain their properties
- explain the base for the spectral- and luminosity classification of stars
- describe the nuclear processes taking place in stellar interiors
- derive temperature dependences of different nuclear burning processes, and the energy released
- use a stellar evolutionary model to derive stellar characteristics
- describe the evolutionary tracks for stars of different masses
- analyze observational characteristics in terms of stellar physics
- explain the role of stars in the chemical evolution of the universe
- describe the end stages of stellar evolution: white dwarfs, neutron stars and black holes
