All about the physics of compact objects in 3 hours Neutron stars and black holes are the final stages of the evolution of massive stars. These compact objects not only have fascinating astrophysical manifestations, but are also of great interest to fundamental physics. It is no wonder that two and a half Nobel Prizes have already been awarded for the study of neutron stars (for the discovery of radio pulsars, for the detection of a double pulsar and the verification of general relativity, and at least half of the prize for the development of X-ray astronomy can be attributed here). The course examines various sources associated with neutron stars and black holes, the evolution of neutron stars, and the prospects for research in this area.
