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…

Evidence for an accretion bridge in the DX Cha circumbinary system from VLTI/MATISSE observations

Tímea Juhász, József Varga, Péter Ábrahám +20

DX Cha (HD 104237) is a spectroscopic binary consisting of a Herbig A7.5Ve-A8Ve primary star and a K3-type companion. Here we report on new micrometer interferometric observ…

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…

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…

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…
