We present spectroscopic observations of the massive multiple system HD\,167971, located in the open cluster NGC\,6604. The brighter component of the triple system is the overcontact eclipsing binary MY\,Ser with an orbital period of 3.32\,days. The radial velocities and the previously published UBV data obtained by \citet{may10} and the UBVRI light curves by \citet{dav88} are analysed for the physical properties of the components. We determine the following absolute parameters: for the primary…

V745 Cassiopean interacting young massive binary in a multiple-star system

We present spectroscopic observations of the massive early type system V745\,Cas, embedded in a multiple star system. The brightest star of the system is the eclipsing binary V745\,Cas with an

Resolved astrometric orbits of ten O-type binaries

Aims. Our long-term aim is to derive model-independent stellar masses and distances for long period massive binaries by combining apparent astrometric orbit with double-lined radial velocity

A VLBI study of the wind-wind collision region in the massive multiple HD 167971

Context. Colliding winds in massive binaries are able to accelerate particles up to relativistic speeds as the result of the interaction between the winds of the different stellar components. HD

MONOS: Multiplicity Of Northern O-type Spectroscopic systems. II. Orbit review and analysis for 35 single-lined spectroscopic binary systems and candidates.

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

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

Long-term XMM–Newton investigation of two particle-accelerating colliding-wind binaries in NGC 6604: HD 168112 and HD 167971

The long-term (over more than one decade) X-ray emission from two massive stellar systems known to be particle accelerators is investigated using XMM-Newton. Their X-ray properties are interpreted

An investigation into the fraction of particle accelerators among colliding-wind binaries - Towards an extension of the catalogue

Particle-accelerating colliding-wind binaries (PACWBs) are multiple systems made of early-type stars able to accelerate particles up to relativistic velocities. The relativistic particles can

The Yarkovsky effect is a thermal radiation force which causes objects to undergo semimajor axis drift and spin up/down as a function of their spin, orbit, and material properties. This mechanism can
