Classification of Upper Sco stars from spectroscopy
I present infrared spectroscopy of 37 brown dwarf candidates in the Upper Scorpius (Upper Sco) association, 35 of which are classified as young and cool, making them likely... -
Angular diameters of 180 stars from the NPOI
We present new angular diameter measurements for 33 stars from the Navy Precision Optical Interferometer, reaching uncertainties on the limb-darkened diameter of 2% or less for... -
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... -
Red-giant stars classification
Determining the ages of red-giant stars is a key problem in stellar astrophysics. One of the difficulties in this determination is to know the evolutionary state of the... -
Metal-rich SX Phe stars in Kepler field
A spectroscopic and photometric analysis has been carried out for 32 candidate SX Phe variable blue straggler stars in the Kepler field. Radial velocities (RVs), space motions... -
New PMS K/M Stars in Upper Scorpius
We present 237 new spectroscopically confirmed pre-main-sequence K- and M-type stars in the young Upper Scorpius subgroup of the Sco-Cen association, the nearest region of... -
Cerro Armazones spectroscopy of F dwarfs
We present a spectroscopic survey of a sample of F stars that have not yet been searched for planets. The observations of 187 stars obtained with the Bochum Echelle... -
Sgr dSph stars spectral classification
We present spectra of 1142 colour-selected stars in the direction of the Sagittarius Dwarf Spheroidal (Sgr dSph) galaxy, of which 1058 were taken with VLT/FLAMES multi-object... -
Spectroscopic Binarity of O and B type stars
The formation of stars above about 20M_{sun} and their apparently high multiplicity remain heavily debated subjects in astrophysics. We have performed a vast high-resolution... -
Automated classification of HIP variables
We present an evaluation of the performance of an automated classification of the Hipparcos periodic variable stars into 26 types. The sub-sample with the most reliable... -
ASAS chromospherically active eclipsing binaries
We have started a spectroscopic survey to identify new chromospherically active components and low-mass pre-main sequence (PMS) stars in recently discovered All Sky Automated... -
2dF survey of the Small Magellanic Cloud
We present a catalogue of new spectral types for hot, luminous stars in the Small Magellanic Cloud. The catalogue contains 4161 objects, giving an order of magnitude increase in... -
Visual multiples. VIII.
A total of 1000 new classifications are given for stars brighter than B=8.0mag in the Aitken double star catalog. The classifications supplement 865 classifications obtained in... -
MK classifications of spectroscopic binaries
New MK spectral classifications are given for 145 spectroscopic binaries (SBs) with A-F primaries because two-dimensional types are lacking for more than one-third of the A-F... -
Galaxy and Magellanic Clouds OB and WR stars
We have generated a set of far-ultraviolet stellar libraries using spectra of OB and Wolf-Rayet stars in the Galaxy and the Large and Small Magellanic Cloud. The spectra were... -
IUE sample of binaries with hot component
We have obtained or retrieved IUE spectra for over 100 middle- and late-type giant and supergiant stars whose spectra indicate the presence of a hot component earlier than type... -
Oxygen-rich dust shells IR spectral classification
This paper presents infrared spectral classifications for a flux-limited sample of 635 optically identified oxygen-rich variables including supergiants and sources on the... -
UBV-beta Database for LS Stars
(Excerpt from the "intro.txt" file) Between 1959 and 1971, the Hamburg and Warner and Swasey Observatories published a seven-volume survey listing intrinsically luminous stars...
