On the Origin of Elements in the Milky Way
The Big Bang only formed hydrogen and helium. All other elements, e.g., the ones we are made of, were subsequently formed in stars. This course discusses how these elements formed and how we can directly measure and probe nucleosynthesis and galactic chemical evolution. The course starts with the solar composition, i.e., the composition of the Solar System that we are ultimately trying to explain. It then goes back to the Big Bang to start with the first nucleosynthesis events. From here on, the course loops through various stellar nucleosynthesis events and discusses observations and measurements along the way that help us to understand how the elements we are all made of formed in the first place.
This course was first held at Brandeis University in Spring 2021 and is geared as an elective course towards advanced undergraduates and early graduate students. The course is design as a mixture between lectures and reading / discussion of original scientific manuscripts.
