Objectives of the course:

The course gives an overview of the formation of the chemical elements in the Universe in the Big Bang, in stars and in stellar explosions. After a brief description of how the abundances of chemical elements are determined through observations, we discuss nuclear reactions and the calculation of thermonuclear reaction-rates. We also discuss how the rates are measured in the laboratory. Then we take a look at nucleosynthesis in the Big Bang and go through the most important stellar burning stages, including the pp-chains, the CNO cycles, helium burning, and advanced burning stages. We also discuss explosive burning, including the s-process and r-process. Finally, we cover some solar-neutrino physics and high-energy cosmic-ray physics.


Learning outcomes and competences:

At the end of the course, the student should be able to:

  • Identify the main astrophysical processes responsible for the synthesis of the chemical elements in the Universe. Identify the most important observational methods used to determine the abundances of the chemical elements.
  • Describe the most important stellar burning stages in stellar evolution, account for their role in nucleosynthesis and identify associated astrophysical sites. This includes the pp-chains, the CNO cycles, helium burning, advanced burning stages and explosive burning stages, such as the s-process and r-process.
  • Make use of equations and graphs to explain central concepts of nuclear astrophysics, such as the Gamow window and resonant and non-resonant reactions.
  • Describe the most important experimental methods used to determine thermonuclear reaction-rates.
  • Carry out simple derivations of relevant equations describing the nuclear-physics processes in stars and apply these to specific problems.
  • Find relevant information, e.g., in the scientific literature, on a research problem/topic. Evaluate the information and convey your conclusions in writing and through oral presentation using scientific/academic terms and language.
