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 cross-identifications with other sources; coordinates (obtained in most cases from Tycho-2 data); astrometric distances for 24 of the nearest stars; optical (Tycho-2, Johnson, and Strömgren) and NIR photometry; group membership, runaway character, and multiplicity information; and a Web-based version with links to on-line… 
THE GALACTIC O-STAR SPECTROSCOPIC SURVEY. I. CLASSIFICATION SYSTEM AND BRIGHT NORTHERN STARS IN THE BLUE-VIOLET AT R ∼ 2500
We present the first installment of a massive spectroscopic survey of Galactic O stars, based on new, high signal-to-noise ratio, R ∼ 2500 digital observations from both hemispheres selected from the
Fundamental Parameters of Early-Type O4 Dwarfs from Galactic O-Stars Spectroscopic Survey
We present a synthetic spectral study of three (9 Sgr AB, HDE 229232 AB and HD 5005 A )galactic early-type O4 dwarf stars with high signal-to-noise ratio (S/N) ∼ 200-300, medium-resolution R∼ 2500
A DETAILED FAR-ULTRAVIOLET SPECTRAL ATLAS OF O-TYPE STARS
In this paper, we present a spectral atlas covering the wavelength interval 930–1188 Å for O2–O9.5 stars using Far-Ultraviolet Spectroscopic Explorer archival data. The stars selected for the atlas

This is the third installment of the Galactic O-Star Spectroscopic Survey (GOSSS), a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R ∼ 2500
THE GALACTIC O-STAR SPECTROSCOPIC SURVEY (GOSSS). II. BRIGHT SOUTHERN STARS
We present the second installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R ∼ 2500 digital observations from both
The Alma catalogue of OB stars – II. A cross-match with Gaia DR2 and an updated map of the solar neighbourhood
We cross-match the Alma catalog of OB stars with Gaia DR2 astrometry and photometry as a first step towards producing a clean sample of massive stars in the solar neighbourhood with a high degree of
Search for Faint Companions to O-stars Using the AEOS 3.6 Meter Telescope
Abstract : O stars are the most massive and luminous main sequence stars in the sky. they are frequently found in clusters of other O and B type stars. Due to the intrinsic brightness of these stars
Galactic Distributions and Statistics of the HD Stars in the Michigan Spectral Catalogue
The systematic, spectroscopic two-dimensional classification of the HD stars by N. H. is approximately three-quarters complete. Over 161,000 stars have been classified visually using 10°
The IACOB spectroscopic database of galactic OB stars
Abstract We present the IACOB spectroscopic database, the largest homogeneous database of high-resolution, high signal-to-noise ratio spectra of Northern Galactic OB-type stars compiled up to date.
Optical-NIR dust extinction towards Galactic O stars
[ABRIDGED] Context. O stars are excellent tracers of the intervening ISM because of their high luminosity, blue intrinsic SED, and relatively featureless spectra. We are currently conducting GOSSS,

The stellar content of Cyg OB2 has been investigated using CCD photometry and spectroscopy. The intrinsically bluest stars have been isolated for spectroscopy by using a reddening-free parameter. The

Distances of Galactic WC stars from emission-line fluxes and a quantification of the WC classification
The extent to which later-type WC stars in the Galaxy show constant flux in the carbon lines is assessed. It is found the the WC stars are an extremely well-behaved sequence in terms of quantitative
