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).
