Revealing the accelerating wind in the inner region of the colliding-wind binary WR 112
John D. Monnier, Yinuo Han, Michael F. Corcoran +17
Colliding winds in massive binaries generate X-ray-bright shocks, synchrotron radio emission, and sometimes even dusty "pinwheel" spirals. We report the first X-ray detections of t…
Evidence for an accretion bridge in the DX Cha circumbinary system from VLTI/MATISSE observations
Tímea Juhász, József Varga, Péter Ábrahám +20
DX Cha (HD 104237) is a spectroscopic binary consisting of a Herbig A7.5Ve-A8Ve primary star and a K3-type companion. Here we report on new micrometer interferometric observ…
Mid-infrared evidence for iron-rich dust in the multi-ringed inner disk of HD 144432
J. Varga, L. B. F. M. Waters, M. Hogerheijde +40
Context. Rocky planets form by the concentration of solid particles in the inner few au regions of planet-forming disks. Their chemical composition reflects the materials in the di…
Wavelength-Dependent Extinction and Grain Sizes in Dippers
Michael L. Sitko, Ray W. Russell, Zachary C. Long +8
We have examined inter-night variability of K2-discovered Dippers that are not close to being viewed edge-on, as determined from previously-reported ALMA images, using the SpeX spe…
The dusty circumstellar environment of Betelgeuse during the Great Dimming as seen by VLTI/MATISSE
E. Cannon, M. Montargès, A. de Koter +23
The 'Great Dimming' of the prototypical red supergiant Betelgeuse, which occurred between December 2019 and April 2020, gives us unprecedented insight into the processes occurring…
Locating dust and molecules in the inner circumstellar environment of R~Sculptoris with MATISSE
Julien Drevon, Florentin Millour, Pierre Cruzalèbes +49
AGB stars are one of the main sources of dust production in the Galaxy. However, it is not clear what this process looks like and where the dust is condensing in the circumstellar…
