FY3451: Astrophysics IIH 2024The course aims to provide a more advanced discussion of selected topics in astrophysics, in particular fusion and nuclear reaction, final stages of stars, high-energy processes plus some extragalactic astrophysics. The course is taught regularly in the autumn semester starting from 2021; the selection of topics is still adaptable. FY2450 Astrophysics (or an equivalent course) is not a prerequisite for this course - but is a useful preparation for "astrophysical" thinking.

We will follow roughly my lecture notes (which are still pretty rough and will be updated during the course), see the link below. The number of excellent text-books on astrophysics is large: Check out the library to find book(s) suitable for you. Some recommend ones are
Lectures notesYou can find a 2023 draft of the notes here, an updated version (1.Nov.) is here, If you find errors, let me know. You can obtain a maximal bonus of 5% for finding errors in the lecture notes: 5% for the student finding most errors, 4% for second most, etc. Email errors to me.Corrections:Language corrections are welcome, but not listed below
