Catalog of positions and B-magnitudes of stars in the circumpolar region of the Northern Sky Survey (FON) project
Andruk, V. M.; Pakuliak, L. K.; Golovnia, V. V. +4 more
The catalog of equatorial coordinates α and δ and B-magnitudes of stars has been created at the Main Astronomical Observatory, National Academy of Sciences of Ukraine (MAO NASU), for the circumpolar region (from 58° to 90°) of the Northern Sky Survey (FON) project within the work on the rational use of resources accumulated in the JDA (Joint Digit…
Variations of the X-ray INTEGRAL spectrum of the active galactic nucleus of NGC 4945
Fedorova, E. V.; Zhdanov, V. I.
Results of 11-year-long X-ray INTEGRAL observations of the nucleus of Seyfert galaxy NGC 4945 in the 3–500 keV range were processed. A two-component spectrum model, which includes strong radiation absorption in the Compton-thick torus around the AGN "central engine" and secondary radiation reflected from the torus walls, was used in the analysis. …
Processing results of digitized photographic observations of Pluto from the collections of the Ukrainian Virtual Observatory
Andruk, V. M.; Shatokhina, S. V.; Protsyuk, Yu. I. +2 more
The catalogue of 59 equatorial coordinates and magnitudes of the Pluto-Charon system for the period 1961–1990 was created based on digitized photographic observations from collections of the Joint Digital Archive of the Ukrainian Virtual Observatory obtained from five telescopes of three Ukrainian observatories. Developed software and scan process…
Compiling catalogs of stellar coordinates and proper motions via coprocessing of archival photographic and modern CCD observations
Andruk, V. N.; Protsyuk, Yu. I.; Kovylianska, O. E. +3 more
A catalog of positions and proper motions of stars in the fields around open clusters was compiled at the Research Institute—Nikolaev Astronomical Observatory (NAO) with the use of the results of photographic observations conducted in the 20th century (at the NAO zonal astrograph with D = 11.6 cm and F = 2.04 m) and modern CCD observations perform…
A study of the photometric system of the Kiev network telescope
Andruk, V. M.; Yatsenko, A. I.; Kleshchonok, V. V. +4 more
We performed a series of CCD observations in BVRI bands of a celestial region in cluster M67 (NGC 2682) to study the photometric system of the Kyiv network telescope. The signal recording system consists of a CGE-1400 telescope, Celestron #94175 focal reducer, an automatic turret with a set of UBVRI filters, and a Rolera Mgi CCD camera. The operat…
Catalog of stars with high proper motions (version 3.0)
Ivanov, G. A.
We compiled a catalog (containing astrometric and astrophysical characteristics) of 4 302 200 stars with high proper motions (no less than 40 mas/year) using original measurements of proper motions of stars from the catalogs FONAK 1.1, HIPPARCOS, "Tycho-2," UCAC2,3, CMC (STAR 11), PPM, PPMX, NPM1, NPM2, XZ80Q, Pul-3, Pul2, NLTT, GCVS, LHS, "Lowell…
Kyiv meridian axial circle with a new CCD camera
Andruk, V. N.; Lazorenko, P. F.; Karbovs'ky, V. L. +4 more
Specifications of a new Apogee Alta U47 CCD camera mounted at the Kyiv meridian axial circle (MAC) are presented. The camera is based on the 1024 × 1024 pxl e2v CCD47-10 with pixel sizes of 13 × 13 µm. Observations are carried out in the scan-drift mode with an effective exposure time of 77 s for equatorial stars. The MAC photometric system …
Cross index list of stars with high proper motions (version 3.0). calibration of magnitudes
Yatsenko, A. I.; Ivanov, G. A.
A cross index list of over 2000000 stars with high proper motions (no less than 0.04″/year) is compiled on the basis of original determinations from the catalog FONAK1.1 and of data from the catalogs HIPPARCOS, Tycho-2, UCAC2, UCAC3, PPMX, CMC (STAR 11), PPM, GCVS, NPM1, NPM2, XZ80Q, PUL2, PUL3, NLTT, LHS, PM2000 (Bordeaux), and XC1 as well as of …
Cross-identifications of stars with high proper motions (Version 2.0)
Ivanov, G. A.
A cross index list of 493 200 stars with proper motions higher than 0.04″/yr (ftp://ftp.mao.kiev.ua/pub/astro/c-ihpms2) was compiled on the basis of the original determinations for the FONAK1.1 catalog stars, the data from the Hipparcos, Tycho-2, UCAC2, CMC (STAR 11), PPM, NPM1, NPM2, XZ80Q, Pul-3, PUL2, GCVS, NLTT, LHS, Lowell Proper Motion, and …
Peculiarities of galactic rotation in the solar neighborhood from the data on red clump giants
Rybka, S. P.
The three-dimensional Ogorodnikov-Milne model was used to investigate the local velocity field on the basis of the tangential velocities of more than 53 000 red giants which were identified as most probable Red Clump members from the Tycho-2 catalog. Galactic rotation parameters were determined for two star groups at the galactic latitudes |b| <…
