WR 112 is a dust-forming carbon-rich Wolf-Rayet (WC) binary with a dusty circumstellar nebula that exhibits a complex asymmetric morphology, which traces the orbital motion and dust formation in the colliding winds of the central binary. Unraveling the complicated circumstellar dust emission around WR 112 therefore provides an opportunity to understand the dust formation process in colliding-wind WC binaries. In this work, we present a multi-epoch analysis of the circumstellar dust around WR… Expand

Massive Binary WR 112 and Properties of Wolf-Rayet Dust
Some hot, massive, Population I Wolf-Rayet (W-R) stars of the carbon subclass are known to be prolific dust producers. How dust can form in such a hostile environment remains a mystery. Here weExpand
Stagnant Shells in the Vicinity of the Dusty Wolf–Rayet–OB Binary WR 112
We present high spatial resolution mid-infrared images of the nebula around the late-type carbon-rich Wolf–Rayet (WC)–OB binary system WR 112 taken by the recently upgraded VLT spectrometer andExpand
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 theirExpand
Detection of a subarcsecond dust shell around the Wolf‐‐Rayet star WR 112
A lunar occultation event of the Wolf-Rayet star WR 112 (type WC9) has been observed simultaneously from two independent telescopes at lambda = 2.2microns, allowing us to investigate this source withExpand
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. Expand
Anisotropic winds in a Wolf–Rayet binary identify a potential gamma-ray burst progenitor
The massive evolved Wolf–Rayet stars sometimes occur in colliding-wind binary systems in which dust plumes are formed as a result of the collision of stellar winds1. These structures are known toExpand
Radio Properties of Pinwheel Nebulae
A small number of dusty Wolf-Rayet stars have been resolved into pinwheel nebulae, defined by their rotating spiral dust shells observed in the infrared. This morphology is naturally explained byExpand
Two Wolf–Rayet stars at the heart of colliding-wind binary Apep
Infrared imaging of the colliding-wind binary Apep has revealed a spectacular dust plume with complicated internal dynamics that challenges standard colliding-wind binary physics. Such challenges canExpand
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 revolvingExpand
Circumstellar Carbonaceous Material Associated with Late-Type Dusty WC Wolf-Rayet Stars
We have studied the 5-8.5 mum infrared spectra of the late-type Wolf-Rayet stars WR 118, WR 112, and WR 104, the WN star WR 147, the B5 hypergiant Cygnus OB2 No. 12, and the Galactic center luminousExpand
