Kyiv Meridian Axial Circle Catalogue (KMAC1) of stars in fields with extragalactic radio sources
Babenko, Yu.; Lazorenko, P.; Karbovsky, V. +3 more
The catalogue of astrometric (positions, proper motions) and photometric (B, V, R, r', J) data of stars in 192 fields with the ICRF objects has been compiled at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine and the Astronomical Observatory of the Kyiv National University. All fields are located in declination zon…
The X1 catalogue of positions and proper motions of faint stars around the ICRF sources
Fedorov, P. N.; Myznikov, A. A.
We present a new catalogue of faint astrometric reference stars around ICRF sources of northern hemisphere. The X1 catalogue is obtained at the Institute of Astronomy of the V. N. Karazin Kharkiv National University and contains about 1.3 million positions and proper motions of stars from 10^m to 19^m within 330 1° ×1° fields. Mean positions and p…
Discovery and study of Comet 67P/Churyumov--Gerasimenko, the main target of the Rosetta space mission
Churyumov, K.
Rosetta, a European space vehicle, which was 15 years in development, headed for short-period Comet 67P/Churyumov-Gerasimenko in February 2004. In September 1969 S. Gerasimenko and the author went to the Alma-Ata Astrophysical Institute to carry out a survey of short-period and new comets. At a later date of that month, the author examined the exp…
Rosetta space mission to Comet 67P/Churyumov--Gerasimenko
Churyumov, K. I.
We present preliminary results of study of middle-resolution optical spectra of Comet 153P/Ikeya--Zhang obtained on May 5, 2002 with the help of the 2.12-m reflector of the Guillermo Haro Astrophysical Observatory. Emission lines of the molecules C2, C3, CN, NH2, CO (Asundi and triplet bands), and H2O
Solution of Earth orientation parameters in the frame of new Earth Orientation Catalogue
Vondr'ak, J.; Ron, C.
The new Earth Orientation Catalogue was recently derived, based mostly on the ARIHIP and Tycho-2 Catalogues that were combined with ground-based optical observations of latitude and Universal Time variations in the 20th century. The solution of Earth orientation parameters, based on this new star catalogue and the new IAU model of precession-nutat…
All-sky census of galactic open cluster stars
Piskunov, A. E.; Kharchenko, N. V.; Scholz, R. D. +2 more
We present the results of a systematic study of the wider neighbourhoods of 520 Galactic open clusters from data of the all-sky high-precision homogeneous catalogue ASCC-2.5. About 30,000 members have been selected on the basis of proper motion, photometric and spatial criteria. Angular and linear sizes of cluster cores and coronas, mean cluster p…
Compiled catalogue of the MK spectral classifications, including astrometric and photometric data and its application
Rybka, S. P.
The catalogue constructed as a tool for stellar kinematic analysis is described. It contains up-to-date information on spectral classifications in the MK system, positions and proper motions in the ICRS system, as well as BV magnitudes for 169,843 single stars. Astrometry and photometry were mainly selected from the Tycho-2. MK spectral types and …
Pulkovo coordinates from astrooptical observations
Gorshkov v., Miller N., Naumov V., Prudnikova E., Shcherbakova N.
The longitude and latitude observations made with two zenith-telescopes and three photoelectric transit instruments of the Pulkovo Observatory during the 20th century were used for coordinates determination. The observations were rereduced in HIPPARCOS reference frame. All known astrometrical reductions and the new model of precession and nutation…
