The extended atmosphere and circumstellar environment of the cool evolved star VX Sagittarii as seen by MATISSE
A. Chiavassa, K. Kravchenko, M. Montargès +50
Context. VX Sgr is a cool, evolved, and luminous red star whose stellar parameters are difficult to determine, which affects its classification. Aims. We aim to spatially resolve t…
ATOMIUM: ALMA tracing the origins of molecules in dust forming oxygen rich M-type stars: Motivation, sample, calibration, and initial results
C. A. Gottlieb, L. Decin, A. M. S. Richards +33
This overview paper presents ATOMIUM, a Large Programme in Cycle 6 with the Atacama Large Millimeter-submillimeter Array (ALMA). The goal of ATOMIUM is to understand the dynamics a…
ATOMIUM: Halide molecules around the S-type AGB star W Aquilae
T. Danilovich, M. Van de Sande, J. M. C. Plane +36
S-type asymptotic giant branch (AGB) stars are thought to be intermediates in the evolution of oxygen- to carbon-rich AGB stars. The chemical compositions of their circumstellar en…
Long Term Evolution of Surface Features on the Red Supergiant AZ Cyg
Ryan P. Norris, Fabien R. Baron, John D. Monnier +23
We present H-band interferometric observations of the red supergiant (RSG) AZ Cyg made with the Michigan Infra-Red Combiner (MIRC) at the six-telescope Center for High Angular Reso…
Atmosphere of Betelgeuse before and during the Great Dimming event revealed by tomography
K. Kravchenko, A. Jorissen, S. Van Eck +7
Despite being the best studied red supergiant star in our Galaxy, the physics behind the photometric variability and mass loss of Betelgeuse is poorly understood. Moreover, recentl…
Atomium: The astounding complexity of the near circumstellar environment of the M-type AGB star R Hydrae. I. Morpho-kinematical interpretation of CO and SiO emission
Ward Homan, Bannawit Pimpanuwat, Fabrice Herpin +36
Evolved low- to intermediate-mass stars are known to shed their gaseous envelope into a large, dusty, molecule-rich circumstellar nebula which typically develops a high degree of s…
High angular resolution polarimetric imaging of the nucleus of NGC 1068: Disentangling the polarising mechanisms
L. Grosset, D. Rouan, F. Marin +8
Polarisation is a decisive method to study the inner region of active galactic nuclei (AGNs) since it is not affected by contrast issues similarly to how classical imaging is. When…
The inner circumstellar dust of the red supergiant Antares as seen with VLT/SPHERE/ZIMPOL
E. Cannon, M. Montarges, A. de Koter +6
The processes by which red supergiants lose mass are not fully understood thus-far and their mass-loss rates lack theoretical constraints. The ambient surroundings of the nearby M0…
