  • UBV Photoelectric Sequences in SA 92-115

    The UBV system was originally defined by ten bright standard stars, primarily in the northern sky. These stars are too bright to be used with large telescopes and cannot be...
  • Photometric and Spectroscopic Databases for LSS Stars

    This catalog contains databases of published photoelectric UBVbeta data, MK-system spectral classifications, and Stroemgren four-color uvby photometry for objects in the...
  • MK, UBV Time and Latitude Stars

    MK spectral classifications are given for 591 stars which are used for time and latitude observations at Mizusawa and Washington. The classifications in the MK system were made...
  • SAO and Supplementary Data

    This SAO catalogue (Smithsonian Astrophysical Observatory Catalogue of 258,997 stars, 1966; see catalog ), connected to the CSI (Catalogue of Stellar Identifications, see...
  • Catalogue of LMC stars

    This catalogue is a compilation of the original data related to stars in the Large Magellanic Cloud (LMC); it concerns essentially the stars brighter than m_pg_=13.5. The list...
  • Photometry and Spectroscopy for Luminous Stars

    This catalogue supersedes the previous version (VI/92). The last update is 01 July 2005. This project originated in the summer of 1991 when the author began compiling a...
  • Galactic O star catalog

    We have produced a catalog of 378 Galactic O stars with accurate spectral classifications that is complete for V<8 but includes many fainter stars. The catalog provides...
  • NGP G5-M stars RV, DDO and BV photometry

    Radial velocities are given for some 900 stars within 15{deg} of the North Galactic Pole, including almost all such stars classified G5 or latter in the Henry-Draper Catalogue...
  • Galactic kinematics from YSOs sample

    Based on published sources, we have created a kinematic database on 220 massive (>10M_{sun}) young Galactic star systems located within <3 kpcof the Sun. Out of them,...
  • New spectral types for Tycho2 stars

    We compare the spectroscopic and trigonometric parallaxes of common stars from the Tycho-2 Spectral Type and Hipparcos Catalogues. This comparison has revealed that the distance...
  • FUSE observations in Magellanic Clouds

    We present an atlas of stellar sight line data from the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite for 287 stars in the Magellanic Clouds, obtained from eight years...
  • Late-type stars toward galactic antirotation

    Low-resolution objective-prism spectra (1360{AA}/mm at H{gamma}) of 184 late-type stars in the Galactic antirotation direction have been obtained with the Curtis Schmidt...
  • MK-like spectral classification

    An MK-like spectral classification has been conducted for 1224 hot subdwarf stars with LAMOST DR9 low-resolution spectra. The whole sample was divided into four categories...
  • M giants in Cassiopeia

    Coordinates and identifications for M-type stars in Cassiopeia Cone search capability for table J/PASJ/33/107/table (Catalog of M-, C- and S-type stars)
  • Stellar Spectral Classification. II.

    The method developed by Stock & Stock (1999RMxAA..35..143S) for stars of spectral types A to K to derive absolute magnitudes and intrinsic colors from the equivalent widths...
  • Hot emission-line stars in LAMOST DR5

    We present a catalog of 3339 hot emission-line stars (ELSs) identified from 451 695 O, B and A type spectra, provided by LAMOST Data Release 5 (DR5). We developed an automated...
  • M-giant star candidates in LAMOST DR 1

    We perform a discrimination procedure with the spectral index diagram of TiO_5_ and CaH_2_+CaH_3_ to separate M giants from M dwarfs. Using the M giant spectra identified from...
  • Nearby stars metallicities

    The catalogue for nearby stars' metallicities has been compiled. The catalogue contains 558 values obtained from photometric UBV data
  • New Wide Common Proper Motion Binaries

    In this work we report the discovery of 150 new double stars of which 142 are wide common proper motion stellar systems. In addition to this, we report the study of 23 recently...
  • L and T dwarf stars

    The establishment of new spectral classes cooler than type M has had a brief, yet already rich, history. Prototypes of the new "L dwarf" and "T dwarf" classes were first found...
