Analyses of multi-epoch, high-resolution (R ~ 50.000) optical spectra of the O-type star HD 152246 (O9 IV according to the most recent classification), complemented by a limited number of earlier published radial velocities, led to the finding that the object is a hierarchical triple system, where a close inner pair (Ba-Bb) with a slightly eccentric orbit (e = 0.11) and a period of 6.0049 days revolves in a 470-day highly eccentric orbit (e = 0.865) with another massive and brighter component A… 
Physical properties of seven binary and higher-order multiple OB systems
Analyses of multi-epoch, high-resolution (~ 50000) optical spectra of seven early-type systems provided various important new insights with respect to their multiplicity. First determinations of
Properties and nature of Be stars 30. Reliable physical properties of a semi-detached B9.5e+G8III binary BR CMi = HD 61273 compared to those of other well studied semi-detached emission-line binaries
Reliable determination of the basic physical properties of hot emission-line binaries with Roche-lobe filling secondaries is important for developing the theory of mass exchange in binaries. It is a
Multiplicity is one of the most fundamental observable properties of massive O-type stars and offers a promising way to discriminate between massive star formation theories. Nevertheless, companions
The orbital elements and physical properties of the eclipsing binary BD+36 3317, a probable member of $\delta$ Lyr cluster
Context. The fact that eclipsing binaries belong to a stellar group is useful, because the former can be used to estimate distance and additional properties of the latter, and vice versa. Aims. Our
Determination of the galactic rotation curve from OB stars
We consider three samples of O- and B-type stars from the solar neighborhood 0.6–4 kpc for which we have taken the distances, line-of-sight velocities, and proper motions from published sources. The
B fields in OB stars (BOB): Concluding the FORS 2 observing campaign
Aims. The B fields in OB stars (BOB) Collaboration is based on an ESO Large Programme to study the occurrence rate, properties, and ultimately the origin of magnetic fields in massive stars. Methods.
Mind Your Ps and Qs: The Interrelation between Period (P) and Mass-ratio (Q) Distributions of Binary Stars
We compile observations of early-type binaries identified via spectroscopy, eclipses, long-baseline interferometry, adaptive optics, common proper motion, etc. Each observational technique is


HD 152246, a new high-mass triple system – preliminary results
Multi-epoch, high-resolution ( R ∼ 50 000) optical spectrosco-py of the O-type (O9 III – IV) star HD 152246 suggests that it is a triple system where a close inner pair (Aa–Ab) with a circular orbit
HD 165246: an early-type binary with a low mass ratio
Analyses of 13 FEROS spectra from the ESO archive and 617 V-band photometric observations from the ASAS3 database allowed us to demonstrate that HD 165246 is a double-lined spectroscopic binary. As
Three-dimensional orbits of the triple-O stellar system HD 150136 ?
Context. HD 150136 is a triple hierarchical system and a non-thermal radio emitter. It is formed by an O3 3.5 V + O5.5 6 V close binary and a more distant O6.5 7 V tertiary. So far, only the inner
