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…

An interferometric mid-infrared study of the eruptive star binary Z CMa with MATISSE/VLTI. I. Imaging the protoplanetary disks during the 2023 outburst

F. Lykou, J. Varga, F. Cruz-Saénz de Miera +14

The mid-infrared (MIR) emitting regions of the individual protoplanetary disks in the binary system Z CMa are resolved by MATISSE/VLTI. The observations were obtained during a sere…

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…
