The complex inner disk of the Herbig Ae star HD 100453 with VLTI/MATISSE

L. N. A. van Haastere, J. Varga, M. R. Hogerheijde +35

The inner regions of planet-forming disks hold invaluable insights for our understanding of planet formation. The disk around the Herbig star HD 100453 presents one such environmen…

The MATISSE view of the inner region of the RY Tau protoplanetary disk

J. S. Martin, J. Kobus, J. Varga +44

The T-Tauri type young stellar object RY Tau exhibits a dust depleted inner cavity characteristic of a transition disk. We constrain the spatial distribution and mineralogy of dust…

Imaging the innermost circumstellar environment of the red supergiant WOH G64 in the Large Magellanic Cloud

K. Ohnaka, K. -H. Hofmann, G. Weigelt +3

Significant mass loss in the red supergiant (RSG) phase has great influence on the evolution of massive stars and their final fate as supernovae. We present near-infrared interfero…

Spatially resolving the AGB star V3 in the metal-poor globular cluster 47 Tuc with VLTI/GRAVITY

Keiichi Ohnaka, Gerd Weigelt, Karl-Heinz Hofmann +1

Mass loss at the asymptotic giant branch (AGB) plays an important role not only in the final fates of stars, but also in the chemical evolution of galaxies. Nevertheless, the metal…

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…

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…
