General Information

The Division of the Relativistic Astrophysics was founded in 1982 by academician Ya.B.Zeldovich. The general scientific activity of the stuff is not a static phenomena, but mainly it lies in the direction, reflected in the famouse book by Ya.B.Zeldovich and I.D.Novikov "Relativistic Astrophysics". The division is one of the finest centers for theoretical astrophysics in Russia.

Scientists of the division are among the national and international leaders in theoretical astrophysics. The research interests of the stuff of the division covers a wide field of the modern theoretical astrophysics. They can be separated into three main branches: "discology" (prof. N.I.Shakura, N. Ketsaris and grad.student G.V. Lipunova); astrophysics of neutron stars, evolution of close binaries and related problems (prof. V.M.Lipunov, prof. K.A.Postnov , drs. M.E.Prokhorov, S.Nazin, I.Panchenko, S.Popov, N. Raguzova, grad. student A. Kuranov and undergraduate students); cosmology (prof. M.V.Sazhin, drs. A.N.Petrov, A.D.Popova, A.V.Toporenski, grad. student V. Ustianski and undergraduate students); microlenzing (prof. M.V.Sazhin and grad. student V. Belokurov.

List of publications of the Division and list of homepages are available via Internet.

Prof. N.I.Shakura -- one of the "father-founders" of the modern theory of accretion disks (so called alpha-disks). His well-known articles in colloboration with R.A.Sunyaev and Ya.B.Zeldovich are among the most citated in the astrophysical literature. Now with his colleagues he works on the physics of selected X-ray binaries (Her X-1, X-ray novae etc). They develope numerical methods of the exploration of such systems.

Physics of close binaries and related phenomenae is one of the main direction of the division. Both: numerical and analitycal methods are used. For the numerical study of the evolution of close binary systems the computer code - "Scenario Machine" - was developed by prof. V.M.Lipunov with collaborators. One of the main feature of the code - advanced calculation of the spin evolution of neutron stars, interacting with matter. The code allows one to get a good statistics of all types of X-ray binaries for different initial parameters. Based on these simulations the gravitational map of the sky was obtained. The results of the modeling are applicated to different regions of star formation. In addition, members of this group are actively interested in a number of other areas: theory of accretion, gravitational waves, astrophysics of compact objects, gamma-ray bursts etc.

A number of very important results were obtained in recent years by the cosmologists of the division. The main ares of investigation of the "cosmological" part of the division are: microlensing and study of the CMB (prof. M.V.Sazhin), quantum cosmology (dr. A.V.Toporenskii and grad. student V. Ustianski), non-orthodoxal cosmology in different spatial dimensions (dr. A.D.Popova), theory of gravitation (dr.A.N.Petrov).
