Spitzer/IRS disk parameters in Serpens
Spectral energy distributions are presented for 94 young stars surrounded by disks in the Serpens Molecular Cloud, based on photometry and Spitzer/IRS spectra. Most of the stars... -
The Wolf-Rayet content of M33 (NGC 598)
Wolf-Rayet (WR) stars are evolved massive stars, and the relative number of WC-type and WN-type WRs should vary with metallicity, providing a sensitive test of stellar... -
Multiple star formation in Taurus-Auriga
We have conducted a high-resolution imaging study of the Taurus-Auriga star-forming region in order to characterize the primordial outcome of multiple star formation and the... -
Variability of low-mass stars in SDSS Stripe 82
We present a catalog of periodic stellar variability in the "Stripe 82" region of the Sloan Digital Sky Survey. After aggregating and re-calibrating catalog-level data from the... -
Revision of MK luminosity classes
The Hipparcos parallaxes of cool giants are utilized in two ways in this paper. First, a plot of reduced parallaxes of stars brighter than 6.5, as a function of spectral type,... -

Volume-limited sample of cool dwarfs. I. L0-T8 dwarfs
We present a new volume-limited sample of L0-T8 dwarfs out to 25pc defined entirely by parallaxes, using our recent measurements from UKIRT/WFCAM along with Gaia DR2 and... -
Orbits of double-lined pairs in multiple stars
Spectroscopic orbits are computed for inner pairs in nine hierarchical multiple systems (HIP 19639, 60845, 75663, 76816, 78163, 78416, 80448, 84789, and HD 105080) and for one... -
Wide-orbit Exoplanet search with IR Direct imaging
We report results from the Wide-orbit Exoplanet search with InfraRed Direct imaging, or WEIRD, a survey designed to search for Jupiter-like companions on very wide orbits... -
Spectroscopic orbits for late-type stars. II.
We have determined spectroscopic orbital elements for 13 systems - 10 single-lined binaries and three double-lined binaries. For the three binaries with previously published... -
Spectroscopy of standard stars
We define an H{alpha} photometric system that is designed as a companion to the well established H{beta} index. The new system is built on spectrophotometric observations of... -
The BUD sample. I. L dwarf activity sample
We present the colors and activity of ultracool (M7-L8) dwarfs from the Tenth Data Release of the Sloan Digital Sky Survey (SDSS). We combine previous samples of SDSS M and L... -
WD within 20pc of the Sun
We present the kinematical properties, distribution of spectroscopic subtypes, and stellar population subcomponents of the white dwarfs within 20pc of the Sun. We find no... -
Catalog of binary UV Ceti stars
A catalogue of nearby UV Ceti type flare stars in (137) visual binary systems is presented in the form of two separate tables of information. The catalogue has developed from... -
Herbig Ae/Be stars candidates
We have observed 42 Herbig Ae/Be stars candidates in both hemispheres using the high resolution spectrographs AURELIE and ELODIE at OHP, and CES at ESO. Table 1 present the... -
Main-sequence companions to massive Be stars
About 20% of all B-type stars are classical Be stars. The Be phenomenon is strongly correlated with rapid rotation, the origin of which remains unclear. It may be rooted in... -
VIPGI spectroscopic templates for FORS2
The goal of this paper is twofold. Firstly, we present F-VIPGI, a new version of the VIMOS Interactive Pipeline and Graphical Interface (VIPGI) adapted to handle FORS2... -
F2-G5 Stars in a North Galactic Pole Region
The catalog is an objective-prism survey for stars of spectral classes F2 to G5 in a region of high galactic latitude. The catalog contains 1127 stars and is complete to a... -
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... -
Spectral Classes in the Galaxy Anticenter
The catalogue is compiled on the basis of the spectral data obtained with the 70-cm meniscus telescope of Abastumani Astrophysical Observatory using the 8{deg} objective prism...
