  • VVVX tile coordinates

    The ESO public survey VISTA Variables in the Via Lactea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from 2009-2015. Upon its conclusion, the...
  • 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...
  • New radio catalogue for M83 SNR and HII regions

    We present a new catalogue of radio sources in the face-on spiral galaxy M83. Radio observations taken in 2011, 2015, and 2017 with the Australia Telescope Compact Array at 5.5...
  • IR and sub-mm variability in protostars

    We study the relationship between the mid-infrared (mid-IR) and sub-millimetre (sub-mm) variability of deeply embedded protostars using the multi-epoch data from the Wide-field...
  • SCUBA-2-COSMOS field brightest sub-mm sources

    We present an ALMA study of the ~180 brightest sources in the SCUBA-2 850-{mu}m map of the COSMOS field from the S2COSMOS survey, as a pilot study for AS2COSMOS - a full survey...
  • Stellar populations of the Ursa Minor dSph galaxy

    We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar...
  • Stellar activity with LAMOST. III.

    We present the results from a systematic study of temporal variation of stellar activity in young late-type stars. We used multi-epoch LAMOST (Large sky Area Multi-Object fiber...
  • New Galactic clusters in the VVVX disc area

    The 'VISTA Variables in the Via Lactea eXtended (VVVX)' ESO Public Survey is a near-infrared photometric sky survey that covers nearly 1700deg^2^ towards the Galactic disc and...
  • Astrometry and photometry of 7 open clusters

    We present a study of seven southern open clusters based on UBVRI CCD photometry (Johnsons-Cousins system) and Gaia DR2 data. Dias4, Dias6, and four other clusters had UBVRI...
  • NGC2548 clumpy spatial and kinematic structure

    NGC 2548 is a ~400-500Myr old open cluster with evidence of spatial substructures likely caused by its interaction with the Galactic disc. In this work we use precise...
  • Proper motions and JHK of 24 Berkeley clusters

    The main astrophysical parameters of 24 previously unstudied open clusters of Berkeley catalogue are presented here. JHK near-infrared (Two Micron All Sky Survey, Cat. II/246)...
  • A VLBA Survey of radio stars in the ONC. I.

    We present first results of a four-epoch VLBA survey for nonthermal emission toward all 556 compact radio sources previously identified in a deep VLA survey of the Orion Nebula...
  • The Quintuplet cluster astrometry and photometry

    We investigate the orbital motion of the Quintuplet cluster near the Galactic center with the aim of constraining formation scenarios of young, massive star clusters in nuclear...
  • Astrometric measurements of HD 143275

    The highly eccentric Be binary system {delta} Sco reached periastron during early 2011 July, when the distance between the primary and secondary was a few times the size of the...
  • Catalog of distant galaxy clusters

    A photographic survey for faint galaxies has been carried out with fine-grained photographic emulsions using the 1.2m Schmidt and 5m Hale telescopes, as well as the 4m Mayall...
  • Corrected proper motion for HIP stars

    The Independent Latitude Stations (INDLS) catalog of proper motion in declination {mu}{delta} for 682 bright Hipparcos (HIP) stars is presented. It is obtained in the Hipparcos...
  • CCD observations of visual double stars

    We present 18365 astrometric observations of 290 visual binaries obtained with the 26-inch refractor of Pulkovo Observatory during 2014-2019. The separation between components...
  • Runaway stars in the 30 Doradus region of the LMC

    We present a catalog of relative proper motions for 368787 stars in the 30 Doradus region of the Large Magellanic Cloud (LMC), based on a dedicated two-epoch survey with the...
