Most Wolf-Rayet stars (WR) of WC9 sub-type exhibit a dusty circumstellar envelope, but it is still a matter of debate how dust can form in their harsh environment. In a few cases, a pinwheel-like structure of the dusty envelope has been detected. Therefore, it has been suggested that dust formation in all dusty WR stars might be linked to colliding winds in a binary system. We probed the innermost region of the circumstellar dust shell of the deeply embedded WR star WR 118. We carried out…

SPHERE view of Wolf-Rayet 104
Context. WR104 is an emblematic dusty Wolf-Rayet star and the prototypical member of a sub-group hosting spirals that are mainly observable with high-angular resolution techniques. Previous aperture
A Radio Pinwheel Emanating from WR 147
Wolf-Rayet (WR) stars are evolved massive stars, presumably on their way to becoming supernova. They are characterized by high luminosities and fast and dense stellar winds. We have detected signs of
The RCB star V854 Centauri is surrounded by a hot dusty shell
Aims : The hydrogen-deficient supergiants known as R Coronae Borealis (RCB) stars might be the result of a double-degenerate merger of two white dwarfs (WDs), or a final helium shell flash in a
Imaging “Pinwheel” nebulae with optical long-baseline interferometry
Abstract Dusty Wolf-Rayet stars are few but remarkable in terms of dust production rates (up to Ṁ = 10−6 M⊙/yr). Infrared excesses associated to mass-loss are found in the sub-types WC8 and WC9. Few
Pinwheels in the sky, with dust : 3D modelling of the Wolf-Rayet 98a environment
The Wolf-Rayet 98a (WR 98a) system is a prime target for interferometric surveys, since its identification as a 'rotating pinwheel nebulae', where infrared images display a spiral dust lane revolving
Sharp images of WR104
Some carbon-rich Wolf-Rayet stars are permanent dust producers, as seen by their infrared excess. In famous targets like WR104, the dust is found in the form of a pinwheel nebula around the central
Numerical simulations and infrared spectro-interferometry reveal the wind collision region in γ^2 Velorum
Colliding stellar winds in massive binary systems have been studied through their radio, optical lines and strong X-ray emission for decades. More recently, near-infrared spectro-interferometric

Impact of orbital motion on the structure and stability of adiabatic shocks in colliding wind binaries
Context. The collision of winds from massive stars in binaries results in the formation of a double-shock structure with observed signatures from radio to X-rays. Aims. We study the structure and


A dusty pinwheel nebula around the massive star WR104
Wolf-Rayet (WR) stars are luminous, massive blue stars thought to be the immediate precursors to some supernovae. The existence of dust shells around such stars has been enigmatic since their
Pinwheel Nebula around WR 98a.
Interpreting the collimated dust outflow in terms of an interacting winds model, the binary orbital parameters and apparent wind speed are derived, consistent with a possible approximately 588 day periodicity in the infrared light curve, linking the photometric variation to the binary orbit.
