Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons protons and neutrons and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang , through nuclear reactions in a process called Big Bang nucleosynthesis. The rest is traces of other elements such as lithium and the hydrogen isotope deuterium. Nucleosynthesis in stars and their explosions later produced the variety of elements and isotopes that we have today, in a process called cosmic chemical evolution. The amounts of total mass in elements heavier than hydrogen and helium called 'metals' by astrophysicists remains small few percent , so that the universe still has approximately the same composition.
Teaching and learning nuclear astrophysics has its challenges as the field crosses multiple disciplines. When teaching nuclear astrophysics, one rarely has all the expertise necessary, and when learning nuclear astrophysics, it can be difficult at a single institution to access the broad range of resources and expertise needed. We therefore offer links to material that should help with teaching nuclear astrophysics, and with self-learning. Graduate level course in stellar physics by Prof. Edward Brown at Michigan State University. Includes numerical MESA exercises.
Students can investigate the physical processes sustaining the energy output of stars during each stage of their evolution and which drive the progression from one stage to the next, and examine the relationship between. Principles of stellar evolution and nucleosynthesis by clayton, d. After the big bang the universe consisted only of h and he and trace amounts of li, be, and b, and it was not until the formation of the first stars that the heavier elements came into existence. Pagel, nucleosynthesis and chemical evolution of galaxies, , cambridge university press, isbn 0 8. Buy stellar evolution and nucleosynthesis 1 by sean ryan, andrew norton isbn. There is a good global agreement over a range of nine orders of magnitude between abundances of 4he, d, 3he and 7li deduced from observations. Coupled with the deuterium abundance it gave us the first determination of the baryon content of the universe.

We will study the observed properties and physics of stars, including their internal structure, energy generation and transport, and their atmospheres. We will examine star formation, stellar evolution, and stellar remnants, including white dwarfs, neutron stars, and black holes. Lamers and E.

Clayton , PDF. Donald D. The basic principles of physics as they apply to the origin and evolution of stars and physical processes of the stellar interior are thoroughly and systematically set out.
The Chemical Evolution of the Galaxy pp Cite as. Here we address the phases of stellar evolution and nucleosynthesis which are more important in connection to chemical enrichment and galactic chemical evolution. In the following one should keep in mind that the stellar evolution results are influenced by the physics adopted in the models. In particular, two physical processes are important in determining the galactic chemical enrichment, the mass loss occurring during various phases of stellar evolution and the treatment of convection. Various types of mixing are expected to occur during the life of a star: convection in central cores, in shells, in external envelopes, overshooting, rotation induced turbulent diffusion. Usually the limit of a stellar convective core is set at the layer where the acceleration of the fluid elements is zero.
