Multi-band infrared imaging reveals dusty spiral arcs around the binary B[e] star 3 Puppis
M. Abello, J. Drevon, A. Meilland +24
3 Puppis is the brightest known B[e] star. Recent work classifies this A-type object as a supergiant, yet the impact of its binarity on the circumstellar environment (CE) remains h…
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…
T CrA has a companion: First direct detection of T CrA B with VLTI/MATISSE
J. Varga, A. Matter, F. Millour +21
T CrA is a Herbig Ae-type young star in a complex circumstellar environment; it includes a circumstellar disk, accretion streamers, jets, and outflows. It has long been suspected t…
Evidence for an accretion bridge in the DX Cha circumbinary system from VLTI/MATISSE observations
TÃmea Juhász, József Varga, Péter Ãbrahám +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…
