Angular diameters of 145 stars from the NPOI
We present new or updated angular diameters, physical radii, and effective temperatures for 145 stars from the Navy Precision Optical Interferometer (NPOI) data archive. We used... -
B supergiants in the LMC
Luminous blue variables (LBVs) exhibit unique variability features, characterized by episodic outbursts (>1mag) accompanied by spectroscopic changes (S Dor variables). It is... -
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...
