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…

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…
