This is the third installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R~2500 digital observations selected from the Galactic O-Star Catalog (GOSC). In this paper we present 142 additional stellar systems with O stars from both hemispheres, bringing the total of O-type systems published within the project to 590. Among the new objects there are 20 new O stars. We also identify 11 new double-lined spectroscopic binaries…

New O-type stars in the LAMOST Data Release 3
In this paper, we present a sample of 27 new Galactic O-type stars found in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 3 (DR3). The new O-stars were
MONOS: Multiplicity Of Northern O-type Spectroscopic systems
Context. Multiplicity in massive stars is key to understanding the chemical and dynamical evolution of galaxies. Among massive stars, those of O type play a crucial role due to their high masses and
The X-ray catalog of spectroscopically identified Galactic O stars
The X-ray emission of O-type stars was first discovered in the early days of the Einstein satellite. Since then many different surveys have confirmed that the ratio of X-ray to bolometric luminosity
The Galactic spiral structure as revealed by O- and early B-type stars
We investigate the morphology and kinematics of the Galactic spiral structure based on a new sample of O- and early B-type stars. We select 6,858 highly confident OB star candidates from the combined
Quantitative spectral classification of Galactic O stars
Our goal is to provide a quantification of several spectral classification criteria for O stars. We collect high-spectral resolution spectra of 105 Galactic O-type stars from various archives. We
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,
A new spectroscopic analysis of the massive O + O type binary HD 54662 AB
HD 54662 AB is one of the three O + OB binaries known so far with orbital period longer than 1000 d, offering the opportunity to test scenarios of massive star formation and models of single
Distances to Galactic OB Stars: Photometry versus Parallax
For application to surveys of interstellar matter and Galactic structure, we compute new spectrophotometric distances to 139 OB stars frequently used as background targets for UV spectroscopy. Many
A Modern Search for Wolf-Rayet Stars in the Magellanic Clouds. IV. A Final Census
We summarize the results of our four year survey searching for Wolf-Rayet (WR) stars in the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). Over the course of this survey we've
Massive stars in the SDSS-IV/APOGEE SURVEY. I- OB stars
In this work we make use of DR14 APOGEE spectroscopic data to study a sample of 92 known OB stars. We developed a near-infrared semi-empirical spectral classification method that was successfully
