Automatic classification of OGLE variables
Scientific exploitation of large variability databases can only be fully optimized if these archives contain, besides the actual observations, annotations about the variability... -
Chromospherically active stars in CoRoT fields
In this paper we report the results of the spectroscopic survey we carried out to detect chromospheric activity of late-type stars in the fields of view of the CoRoT space... -
Velocities in SMC field of NGC 330
We search for the effects of metallicity on B and Be stars in the Small and Large Magellanic Clouds (SMC and LMC) and in the Milky Way (MW), by extending our previous analysis... -
Rosat North Ecliptic survey stellar population
X-ray surveys are a very efficient mean of detecting young stars and therefore allow us to study the young stellar population in the solar neighborhood and the local star... -
Spectroscopic distances of 322 NLTT stars
Distance estimates based on low-resolution spectroscopy and Two Micron All Sky Survey (2MASS, Cat. ) J magnitudes are presented for 322 nearby candidates from Luyten's NLTT... -
32 DENIS nearby red dwarfs
We present spectra of 36 nearby star candidates and 3 red giant candidates, identified in the DENIS database. 32 of the dwarf candidates are nearby red dwarfs, with spectral... -
VLT-FLAMES survey of massive stars
We introduce a new survey of massive stars in the Galaxy and the Magellanic Clouds using the Fibre Large Array Multi-Element Spectrograph (FLAMES) instrument at the Very Large... -
Hipparcos parallaxes of O stars
We compare the absolute visual magnitude of the majority of bright O stars in the sky as predicted from their spectral type with the absolute magnitude calculated from their... -
Havlen-Moffat No. 1 UBVRI photometry
A deep CCD UBVRI photometric survey combined with UBVRI polarimetric observations of 21 bright stars was carried out in the region of the open cluster Havlen-Moffat No. 1. Our... -
Quantitative spectral classification
New criteria of quantitative spectral classification have been introduced and the method of stepwise linear regression to these criteria for quantitative spectral classification... -
Revised spectral types of B-supergiants in the SMC
The problem of the classification of metal poor stars, such as occur in the Small Magellanic Cloud (SMC), is discussed with reference to the applicability of the MK system in... -
Double stars of equal components
A list of 271 double stars of nearly equal components with separations up to about one minute of arc is given. Their physical nature is demonstrated by their spectral type... -
Galactic O Stars
The catalog is a compilation of published data for 644 galactic O stars of luminosity class V. The catalog is intended to be useful to O-type star observers by providing a... -
Michigan Catalogue of HD stars, Vol.3
Please refer to the 'doc.txt' file by Robert S. Hill Cone search capability for table III/80/vol3 (The Catalogue (vol.3)) -
MK Classification Extension
The catalog provides classifications on the Morgan-Keenan (MK) system published in the literature since the appearance of the La Plata catalog (Jaschek et al., 1964). In... -
MK Classification for HD stars for 25-30{deg} zone
The catalog contains MK spectral classifications for 1003 HD stars in the zone +25-30{deg}, briefly presented at IAU Colloq. 47, held in Vatican City in July 1978... -
Stars classified from S2/68 UV line features
This catalog provides the spectral classifications of 1900 stars from the papers listed in References. The classifications were made from spectra obtained by the S2/68 sky... -
Michigan Catalogue of HD stars, Vol.2
This catalog represents the second volume of the University of Michigan systematic reclassification of the Henry Draper Catalogue (HD) stars on the MK system. Volume 2 contains... -
Selected MK Spectral Types
The catalog provides a single spectral type for each star listed in the La Plata catalog (Jaschek, Conde and de Sierra 1964; catalog ) and in the MK Extension (Kennedy 1978; see... -
Michigan catalogue for the HD stars, vol. 1
This catalog represents the first volume of the University of Michigan systematic reclassification of the Henry Draper Catalogue (HD) stars on the MK system. It contains all HD...
