are created. While hydrogen and helium where made during the Big Bang, the heavier
elements from carbon and oxygen up to lead and uranium are produced by nuclear
reactions (fusion, fission, decay) inside stars. We will cover: the different
nucleosynthetic processes in stars, from hydrogen burning to neutron captures; the
stellar sites where they occur, how the freshly made elements are ejected into the
interstellar medium from where new stars are born, and how this processes drive the
chemical evolution of galaxies. Observational constraints to the theories and models
will be presented, including spectroscopic observations and meteoritic stardust
grains. The course will also explain the role of radioactive nuclei in measuring
cosmic times and in deepening our understanding of the origin of the chemical matter
that ended up in the Solar System and the circumstances of the birth of the Sun.Specifically, the following topics will be addressed:
- a historical prospective
- the 8 nucleosynthetic processes
- abundances, how do we describe them
- becoming familiar with the nuclide chart
- nuclear reaction rates and notations
- equations for nuclear reaction networks
- stellar sites of the processes: from low-mass to massive stars
(AGB stars, core collapse supernovae, thermonuclear supernovae and novae)
- details of neutron capture processes
- the chemical evolution of the Galaxy
- spectroscopic observations
- meteoritic data: from stardust to whole rocks, the role of cosmochemistry
- radionuclei as clocks
- radioactivity and habitabilityTo explain the main concepts up-front lecturing and interactive excersises will be
employed together. Hand-on tools such as the nuclide chart as well as current online
databases of nuclear reaction rates will be used. Please bring a laptop to access these files and databases. One laptop can be shared between two students.
