VLTI/MATISSE observations of the hot dust around Pictoris: Observing faint objects with MATISSE
P. Priolet, J. -C. Augereau, J. Milli +32
Context: Hot exozodiacal dust has been detected around approximately 20% of nearby main-sequence stars, indicating that it is a common feature of extrasolar planetary systems. Howe…
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…
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…
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…
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…
High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
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…
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…
Improving the diameters of interferometric calibrators with MATISSE
S. Robbe-Dubois, P. Cruzalèbes, Ph. Berio +16
A good knowledge of the angular diameters of stars used to calibrate the observables in stellar interferometry is fundamental. As the available precision for giant stars is worse t…
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…
VLTI-MATISSE L- and N-band aperture-synthesis imaging of the unclassified B[e] star FS Canis Majoris
K. -H. Hofmann, A. Bensberg, D. Schertl +58
Context: FS Canis Majoris (FS CMa, HD 45677) is an unclassified B[e] star surrounded by an inclined dust disk. The evolutionary stage of FS CMa is still debated. Perpendicular to t…
MATISSE, the VLTI mid-infrared imaging spectro-interferometer
B. Lopez, S. Lagarde, R. G. Petrov +150
Context:Optical interferometry is at a key development stage. ESO's VLTI has established a stable, robust infrastructure for long-baseline interferometry for general astronomical o…
First MATISSE L-band observations of HD 179218. Is the inner 10 au region rich in carbon dust particles?
E. Kokoulina, A. Matter, B. Lopez +58
Carbon is one of the most abundant components in the Universe. While silicates have been the main focus of solid phase studies in protoplanetary discs (PPDs), little is known about…
Mid-infrared circumstellar emission of the long-period Cepheid l Carinae resolved with VLTI/MATISSE
V. Hocdé, N. Nardetto, A. Matter +149
The nature of circumstellar envelopes (CSE) around Cepheids is still a matter of debate. The physical origin of their infrared (IR) excess could be either a shell of ionized gas, o…
NAOMI: the adaptive optics system of the Auxiliary Telescopes of the VLTI
Woillez J., Abad J. A., Abuter R. +80
The tip-tilt stabilisation system of the 1.8 m Auxiliary Telescopes of the Very Large Telescope Interferometer was never dimensioned for robust fringe tracking, except when atmosph…
