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. 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.

At the end of the course the student is able to:
quantitatively explain the basic properties of degenerate matter and its origins.
quantitatively explain the consequences of degenerate matter for compact object formation and structure.
explain the processes determining formation and structure of neutron 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, and light motion in a Schwarzschild geometry.
explain in general terms consequences of Kerr geometry.
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.
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.

Dit vak hanteert de algemene ‘Fraude- en plagiaatregeling’ van de UvA. Onder plagiaat of fraude wordt verstaan het overschrijven van het werk van een medestudent dan wel het kopiëren van wetenschappelijke bronnen (uit bijvoorbeeld boeken en tijdschriften en van het Internet) zonder daarbij de bron te vermelden. Uiteraard is plagiaat verboden. Hier wordt nauwkeurig op gecontroleerd en streng tegen opgetreden. Bij verdenking van plagiaat wordt de examencommissie van de opleiding ingeschakeld. Wanneer de examencommissie overtuigd is dat er plagiaat gepleegd is dan kan dit maximaal leiden tot een uitsluiting van al het onderwijs van de opleiding voor een heel kalenderjaar. Zie voor meer
