In this paper, I present a general discussion of several astrophysical processes likely to play
a role in the production of non-thermal emission in massive stars, with emphasis on massive …

Massive stars are crucial building blocks of galaxies and the universe, as production sites of
heavy elements and as stirring agents and energy providers through stellar winds and …

Context. LS 5039 and LS I+ 61° 303 are unique amongst high-mass X-ray binaries (HMXB)
for their spatially-resolved radio emission and their counterpart at> GeV gamma-ray …

Colliding winds of massive star binary systems are considered as potential sites of
nonthermal high-energy photon production. Motivated by the detection of synchrotron radio …

We use hydrodynamical models of the wind-collision region in the archetype colliding-wind
system WR 140 to determine the spatial and spectral distributions of the radio, X-ray, and γ …

Abstract Milliarcsecond resolution Very Long Baseline Array (VLBA) observations of the
archetype W-R+ O star colliding-wind binary (CWB) system WR 140 are presented for 23 …

The dynamics of the wind–wind collision in massive stellar binaries are investigated using
3D hydrodynamical models which incorporate gravity, the driving of the winds, the orbital …

The X-ray emission from the wind–wind collision in short-period massive O+ O star binaries
is investigated. The emission is calculated from 3D hydrodynamical models which …

We present radiative-transfer modelling of the dusty spiral Pinwheel Nebula observed
around the Wolf–Rayet/OB-star binary WR 104. The models are based on the three …

We present a model for the creation of non-thermal particles via diffusive shock acceleration
in a colliding-wind binary. Our model accounts for the oblique nature of the global shocks …
