Context. Stellar rotation is an important parameter in the evolution of massive stars. Accurate and reliable measurements of projected rotational velocities in large samples of OB stars are cruci al to confront the predictions of stellar evolutionary mode ls with observational constraints. Aims. We reassess previous determinations of projected rotational velocities (v sin i) in Galactic OB stars using a large, high quality spectroscopic dataset, and a strategy which account for other sources of… 
Spectroscopic and physical parameters of Galactic O-type stars. II. Observational constraints on projected rotational and extra broadening velocities as a function of fundamental parameters and stellar evolution
Rotation is of key importance for the evolution of hot massive stars, however, the rotational velocities of these stars are difficult to determine. Based on our own data for 31 Galactic O stars and
Projected Rotational Velocities of 136 Early B-type Stars in the Outer Galactic Disk
We have determined projected rotational velocities, v sin i, from Magellan/MIKE echelle spectra for a sample of 136 early B-type stars having large Galactocentric distances. The target selection was
The IACOB project: III. New observational clues to understand macroturbulent broadening in massive O- and B-type stars ?
Context. The term macroturbulent broadening is commonly used to refer to a certain type of non-rotational broadening affecting the spectral line profiles of O- and B-type stars. It has been proposed
The IACOB project
Context. The apparent lack of massive O-type stars near the zero-age main sequence, or ZAMS (at ages <2 Myr), is a topic that has been widely discussed in the past 40 yr. Different explanations for
The IACOB project: II. On the scatter of O-dwarf spectral type -- effective temperature calibrations
We are now in an era of large spectroscopic surveys of OB-type stars. Quantitative spectroscopic analysis of these modern datasets is enabling us to review the physical properties of blue massive
Spectroscopic and physical parameters of Galactic O-type stars. III. Mass discrepancy and rotational mixing
Context. Massive stars play a key role in the evolution of galaxies and our Universe. Aims. Our goal is to compare observed and predicted properties of single Galactic O stars to identify and
Critical study of the distribution of rotational velocities of Be stars. I. Deconvolution methods, effects due to gravity darkening, macroturbulence, and binarity
Context. Among intermediate-mass and massive stars, Be stars are the fastest rotators in the main sequence (MS) and, as such, these stars are a cornerstone to validate models of structure and
Variability of OB stars from TESS southern Sectors 1–13 and high-resolution IACOB and OWN spectroscopy
Context. The lack of high-precision long-term continuous photometric data for large samples of stars has impeded the large-scale exploration of pulsational variability in the OB star regime. As a
A census of massive stars in NGC 346
Spectroscopy for 247 stars towards the young cluster NGC 346 in the Small Magellanic Cloud has been combined with that for 116 targets from the VLT-FLAMES Survey of Massive Stars. Spectral
Spectroscopic Line Modeling of the Fastest Rotating O-type Stars
We present a spectroscopic analysis of the most rapidly rotating stars currently known, VFTS 102 ( vesini=649±52 km s−1; O9: Vnnne+) and VFTS 285 ( vesini=610±41 km s−1; O7.5: Vnnn), both members of
