ON THE ADVANTAGES OF PHOTOMETRIC OBSERVATIONS OF THE GEOSTATIONARYSATELLITES AT SMALL PHASE ANGLES
As a rule, to determine photometric and dynamic characteristics of geostationary satellites required for their identification, long-lasting (from a half of the yearto one year) photometricobservations are needed at GSS d...
SPECTROSCOPIC VARIABILITY OF THE SUPERGIANTS HD21389 AND HD187982
It has been revealed that absorption in the line of Hα has complex structure in the spectrum of the star HD21389 depending on the activity phase of the atmosphere. The profile of the line has inverse P Cyg type in the ac...
X-RAY SPECTRAL PROPERTIES OF THE ISOLATED AGNs: NGC 1050, NGC 2989, ESO 317-038, ESO 438-009
We have analyzed the spectral data obtained by XMM-Newton, Swift, Chandra, and INTEGRAL space observatories for several isolated AGNs from 2MIG catalogue, for which the available X-ray data were accessed. Among these obj...
