High-angular-resolution ALMA imaging of the inhomogeneous dynamical atmosphere of the asymptotic giant branch star W Hya
K. Ohnaka, K. T. Wong, G. Weigelt +1
We present high-angular-resolution imaging of the asymptotic giant branch star W Hya with the Atacama Large Millimeter/submillimeter Array (ALMA) to probe the dynamics and chemistr…
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…
Contemporaneous high-angular-resolution imaging of the AGB star W Hya in vibrationally excited H2O lines and visible polarized light with ALMA and VLT/SPHERE-ZIMPOL
K. Ohnaka, K. T. Wong, G. Weigelt +1
We present contemporaneous high-angular-resolution millimeter imaging and visible polarimetric imaging of the nearby asymptotic giant branch (AGB) star W Hya to better understand t…
Images of Betelgeuse with VLTI/MATISSE across the Great Dimming
J. Drevon, F. Millour, P. Cruzalèbes +31
From Nov. 2019 to May 2020, the red supergiant star Betelgeuse experienced an unprecedented drop of brightness in the visible domain called the great dimming event. Large atmospher…
