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…
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…
Time-resolved protoplanetary disk physics in DQ Tau with JWST
Á. Kóspál, P. Ábrahám, V. V. Akimkin +17
Accretion variability is ubiquitous in YSOs. While large outbursts may strongly affect the disk, the effects of moderate bursts are less understood. We aim to study the physical re…
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…
