  • Astrometric study of ADS 48

    The series of relative positions of the hierarchical triple system ADS 48 ABF (AB=6",AF=327") obtained with the 26-inch Pulkovo refractor during 1961-1995 and measured with the...
  • M 31 reference catalog

    We compiled a catalog of 421 references 12-15mag stars for determining accurate positions of objects in the region of M 31. We also compiled a star chart, which is provided as...
  • Star kinematics catalog in 19 Kapteyn's areas

    1214 individual measurements of radial velocities made with CORAVEL-type spectrometer (Tokovinin, 1987AZh....64..196T) are presented for 1134 stars in 19 northern Kapteyn's...
  • Identification and coordinates in M 53

    Equatorial coordinates have been determined for 61 variables in the northern globular cluster M 53 and for 12 variables in the southern globular cluster NGC 2808 with accuracy...
  • Identification and coordinates in M4

    Accurate equatorial coordinates have been determined for 54 variable stars in the globular cluster M 4=NGC 6121. Cone search capability for table J/PAZh/22/847/table12...
  • Identification and coordinates in M5

    Accurate equatorial coordinates have been determined for 143 variable and suspected variable stars in the globular cluster M5=NGC 5904. For 28 stars, identifications with...
  • Identification and coordinates in NGC 5272

    Equatorial coordinates of variable stars in the globular cluster M3 (NGC 5272) and its nearest surroundings, mainly measured on a plate taken with The Zeiss-1000 telescope, are...
  • Color panorama image of the Milky Way

    This article describes the assembly of an optical (RGB) all-sky mosaic image with an image scale of 36"/pix, a limiting magnitude of approximately 14mag, and an 18 bit dynamic...
  • Accurate Positions for MCG Galaxies

    We have measured accurate celestial coordinates for over 4000 extragalactic objects primarily drawn from a list of MCG galaxies with no recently published accurate positions. We...
  • Revised coordinates for SGC galaxies

    We have determined improved positions for 373 galaxies listed in the Southern Galaxy Catalogue of Corwin, de Vaucouleurs, and de Vaucouleurs (1985, Cat. VII/116) as having poor...
  • Observations of the Galilean moons

    Results of observations of the Galilean moons of Jupiter were carried out at the Normal Astrograph of the Pulkovo Observatory in 2018. We obtained 452 positions of the Galilean...
  • Galilean moons positions

    Results of the Galilean moons observationals taken with Normal Astrograph of the Pulkovo Observatory in 2016-2017 are presented. 761 positions of the Galilean moons of Jupiter...
  • Galilean moons & Jupiter positions

    Observational results are presented for Jupiter and its Galilean moons from the Normal Astrograph at Pulkovo Observatory in 2013-2015. The following data are obtained: 154...
  • Galilean satellites & Jupiter positions

    For observational period of 2009-2011 we have obtained 140 positions of Galilean satellites and 42 calculated positions of Jupiter in the system of UCAC4 catalogue (ICRS,...
  • CCD observations of saturnian satellites

    The astrometric positions of seven saturnian satellites are presented. Positions were derived from more then 5000 CCD frames taken with 26-inch Zeiss refractor at Pulkovo from...
  • Corrected proper motion for HIP stars

    During the last century, there were many so-called independent latitude (IL) stations with the observations which were included into data of a few international organizations...
  • Corrections to HIP proper motions

    We used the data on latitude variations obtained from observations with 10 classical photographic zenith tubes (PZT) in order to improve the Hipparcos proper motions in...
  • Candidate halo dark matter

    The Milky Way galaxy contains a large, spherical component which is believed to harbor a substantial amount of unseen matter. Recent observations indirectly suggest that as much...
  • Standard errors for PPM and Tycho stars

    The connection between the optical reference frame and the radio one constitutes one of the main purposes of the astrometry. The paper is pointing out the contribution of the...
  • Optical coordinates of southern PNe

    A homogeneous set of new measurements of nearly all (995 out of 1007) objects from the Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Cat. ) or in the first supplement...
