We present the analysis performed on spectropolarimetric data of 97 O-type targets included
in the framework of the MiMeS (Magnetism in Massive Stars) Survey. Mean Least-Squares …

We present the results of a speckle interferometric survey made with the CHARA speckle
camera and 4 m–class telescopes of Galactic O-type stars with V< 8. We can detect with the …

We present a catalogue of homogeneous measures of the linewidth parameter, ve sin i, for
373 O-type stars and early B supergiants (including the separate components of 25 binary …

The majority of close massive binary stars with initial periods of a few days experience a
contact phase, in which both stars overflow their Roche lobes simultaneously. We perform …

Abstract V606 Centauri (V606 Cen) is an early B-type close binary with an orbital period of
1.4950935 days, and its complete light curves are very difficult to observe on the ground. By …

Stellar evolutionary models are often used to infer a star's mass via its luminosity, but
empirical checks on the accuracy of the theoretical mass-luminosity relation for very massive …

Photometric analysis and spectroscopic study of the long-period low-mass-ratio deep-
contact binary KN Per were performed. The light curves of the BV (RI) c band were from the …

A procedure for the automatic classification of eclipsing binaries is presented. The
procedure is based on the data from 1029 classified systems and allows for the classification …

Context. Given that mergers are often invoked to explain many exotic phenomena in
massive star evolution, understanding the evolutionary phase directly preceding a merger …

A catalog of massive (⩾ 10 M⊙) stars in binary and multiple systems with well-known
masses and luminosities has been compiled. The catalog is analyzed using a theoretical …
