Course content

The course provides an introduction to the astrophysics of compact objects and their environments, as well as to the basic theoretical ideas by which we think we can understand these objects. The focus is on the conceptual background necessary to interpret astronomical observations of compact objects. Students learn to understand the basic properties of degenerate matter and its consequences for stellar structure, get a first exposure to the description of black holes in terms of curved spacetimes and its predicted observational consequences. Students obtain a quantitative insight into some of the astrophysical processes resulting from the unique characteristics of compact objects that lead to observable phenomena: relativistic motions, accretion, spin power, equation of state of neutron stars. Students obtain an understanding of the observational characteristics of the various systems in which compact objects are found: white dwarfs, cataclysmic variables, X-ray binaries, radio pulsars, magnetars, and how these can be related to the physical properties of these compact objects.

Objectives

• quantitatively explain the basic properties of degenerate matter and its origins and their consequences for compact object formation and structure.
• explain the processes determining formation and structure of compact stars and quantitatively the role of degenerate electrons and neutrino diffusion therein.
• explain in general terms the relativity principle and the equivalence principle, and to provide a general outline of GR in terms of the field equation and the energy momentum tensor.
• explain the concept of curved spacetimes, and to quantitatively derive consequences for space and time intervals, light motion (bending, Shapiro delay); explain qualitatively the nature of the event horizon and singularity in a Schwarzschild geometry.
• explain in general terms the structure and consequences of Kerr geometry; ergosphere, Penrose process, horizons and singularity
• quantitatively explain the motions and conservation of energy and angular momentum in accretion disks.
• quantitatively explain observational characteristics of supernovae, radio pulsars, X-ray binaries, active galactic nuclei and gamma-ray bursts and how these are related to the physical properties of compact objects and the surrounding spacetime. 

Teaching methods

• Hoorcollege
• Werkcollege
• Lecture
• Seminar
• Self-study

In the oral lectures the subject material is presented by active researchers in the field. These lectures are supplemented by exercise classes (werkcolleges) where students actively apply the theoretical and practical materials in calculations relevant to compact object astrophysics.

Learning activities

Attendance

Programme's requirements concerning attendance (TER-B):

• Each student is expected to participate actively in each component of the programme that he/she signed up for. A student that does not attend the first two seminars of a course, will be administratively removed from the seminar group. A request for reregistration for the seminars can be applied to the programme coordinator.
• If a student cannot attend an obligatory component of a programme's component due to circumstances beyond his control, he must report in writing to the relevant teacher as soon as possible. The teacher, if necessary after consulting the study adviser, may decide to issue the student a replacing assignment.
• It is not allowed to miss obligatory commponents of the programme if there is no case of circumstances beyond one's control.
• In case of participating qualitatively or quantitatively insufficiently, the examiner can expel a student from further participation in the programme's component or a part of that component. Conditions for sufficient participation are set down in advance in the course manual.
• In addition to the above mentioned rules, in the first semester of the first year a student should be present in at least 80% of the seminars. Moreover, participation to midterm tests and obligatory homework is required. If the student does not comply with these obligations, the student is expelled from the resit of this course. Students in the double Bachelor's degree programme Mathematics and Physics are exempted from this requirement. In case of personal circumstances, as described in OER-A Article A-6.4, a different study plan will be made in consultation with the study advisor.
