Interferometric Detection and Orbit Modeling of the Subcomponent in the Hot-dust System Tuc A: A Low-mass Star on an Eccentric Orbit in a Hierarchical-quintuple System
T. A. Stuber, A. Mérand, F. Kirchschlager +19
The system Tuc A is part of a hierarchical-quintuple system and is a prime target for studies of hot-exozodiacal dust, because a time-variable near-infrared excess has been det…

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…

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…
