MATISSE unveils a dusty disc in the interior of EP Aquarii. First evidence of a misaligned hierarchical triple system with a central AGB star?
J. Alonso-Hernández, C. Paladini, C. Sánchez Contreras +26
Aims. We have mapped the dust and molecular gas emission distributions in the vicinity (a few stellar radii) of the asymptotic giant branch (AGB) star EP\,Aquarii, with a previousl…
The mid-infrared spectrum of Pictoris b. First VLTI/MATISSE interferometric observations of an exoplanet
M. Houllé, F. Millour, P. Berio +46
Few spectra of directly-imaged exoplanets have been obtained in the mid-infrared (> 3 m). This region is particularly rich in molecular spectral signatures, whose measurements c…
Circumstellar emission of Cepheids across the instability strip: Mid-infrared observations with VLTI/MATISSE
V. Hocdé, A. Matter, N. Nardetto +14
The circumstellar envelopes (CSE) of Cepheids are still not well characterized despite their potential impact on distance determination via both the period-luminosity relation and…
GRAVITY for MATISSE -- Improving the MATISSE performance with the GRAVITY fringe tracker
J. Woillez, R. Petrov, R. Abuter +23
Context: MATISSE, the mid-infrared spectro-imaging instrument of VLTI, was designed to deliver its advertised performance when paired with an external second generation fringe trac…
An impressionist view of V Hydrae. When MATISSE paints Asymmetric Giant Blobs
L. Planquart, C. Paladini, A. Jorissen +29
Our purpose is to study the effect of binary companions located within the first 10 stellar radii from the primary AGB star. In this work, we target the mass-losing carbon star V H…
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…
A dusty veil shading Betelgeuse during its Great Dimming
M. Montargès, E. Cannon, E. Lagadec +24
Red supergiants are the most common final evolutionary stage of stars that have initial masses between 8 and 35 times that of the Sun. During this stage, which lasts roughly 100,00…
Grown-up stars physics with MATISSE
Florentin Millour, J Hron, A Chiavassa +20
MATISSE represents a great opportunity to image the environment around massive and evolved stars. This will allow one to put constraints on the circumstellar structure, on the mass…
