A static spherically symmetric gravitational field in the kaluza-klein theory

In the context of the Kaluza-Klein theory we obtain the external solution for the gravitational field generated by a static spherically symmetric distribution of neutral and charged matter. We obtain a formula that connects the mass of the central body with the integral of the pressure distribution inside it.Translated fromAstrofizika, Vol. 38, No. 3, 1995.     

Magnetosphere of barionic stars

Conclusions Our chief result is the proof that pulsars can possess a quasi-steady-state magnetosphere with temperature T10⁴–10⁶. The magnetosphere can be maintained in this state in its part nearest the star if the plasma is heated by radiation from the star (except for P 0531, for which such radiation is nearlyinsignificant). Plasma in the main part of the magnetosphere is maintained in such a hot state as a result of Joule heat due to drift currents. Radiation from the magnetosphere of P 0531 is found basically in the optical spectrum, though the intensity is several orders of magnitude less than the observed value, so that it does not correspond to the observed optical emission from the pulsar in the Crab nebula.Erevan State University.

Physics of the solar-terrestrial coupling: Results,problems, and new approaches

The results of the works performed in the field of the most actual problems of physics and optics of the solar-terrestrial coupling have been analyzed. This is the problem of energy in the ionospheric physics, considered because space monitoring of the solar irradiance ionizing the upper ionosphere is still absent. These are the problems of transformation of the solar flare energy and corpuscular precipitation into the microwave ionospheric radiation. Finally, this is the main problem of present-day natural science: the physical mechanism of the solar-terrestrial coupling as applied to the explanation of the detected correlations in the Sun-weather and the Sun-biosphere systems. A unified physical (radio-optical) mechanism for controlling the processes in the lower atmosphere and biosphere (including human being), dependent on the level of solar and geomagnetic activity and related to the ionospheric microwave radiation in transitions between the optically highly excited (Rydberg) states of all components of the upper atmosphere, has been considered.     

Change in the Orbital Period of a Binary System Due to an Outburst in a Windy Accretion Disk

Astronomy Letters - We consider a new mechanism for the removal of angular momentum from an X-ray binary system and the change in its orbital period—the mass loss in the form of a wind from...
