Proper Motions of 59 766 Stars Absolutized Using Galaxies in 149 Sky Fields (PUL2)
Bobylev, V. V.; Shakht, N. A.; Bronnikova, N. M.
The PUL2 catalog has been photographically compiled in Pulkovo according to Deutch's plan. The catalog contains the mean coordinates of stars in the ICRS system at epoch J2000.0 and their original absolute proper motions. The photographic observations were performed with a normal astrograph. The first and second epochs of the photographic plates a…
Kinematic Control of the Inertiality of ICRS Catalogs
Bobylev, V. V.
We perform a kinematic analysis of the HIPPARCOS and TRC proper motions of stars by using a linear Ogorodnikov-Milne model. All of the distant (r > 0.2 kpc) stars of the HIPPARCOS catalog have been found to rotate around the Galactic y axis with an angular velocity of M_{13}^- = -0.36 +/- 0.09 mas/yr. One of the causes of this rotation may be a…
Occultations of Stars Brighter Than 15 mag by the Largest Trans-Neptunian Objects in 2004-2014
Denissenko, D. V.
We computed the occultations of stars brighter than 15 mag by the largest trans-Neptunian objects (TNOs) for the next ten years. In our search, we used the following catalogs: Hipparcos; Tycho2 with the coordinates of 2838666 stars taken from UCAC2 (Herald 2003); and UCAC2 (Zacharias et al. 2003) with 16356096 stars between 12.00 mag and 14.99 mag…
