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…
Edge-On Disk Study (EODS) II: HCO and CO vertical stratification in the disk surrounding SSTTau042021
C. Foucher, A. Dutrey, V. Piétu +17
Context. Edge-on disks offer a unique opportunity to directly examine their vertical structure, providing valuable insights into planet formation processes. We investigate the dust…
Edge-On Disk Study (EODS) III: Molecular Stratification in the Flying Saucer Disk
A. Dutrey, O. Denis-Alpizar, S. Guilloteau +22
Context: Investigating the vertical distribution of molecular content in protoplanetary disks remains difficult in most disks mildly inclined along the line of sight. In contrast,…
Time-resolved protoplanetary disk physics in DQ Tau with JWST
Ã. Kóspál, P. Ãbrahám, 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…
Time-dependent response of protoplanetary disk temperature to an FU Ori-type luminosity outburst
S. I. Laznevoi, V. V. Akimkin, Ya. N. Pavlyuchenkov +3
Context. The most prominent cases of young star variability are accretion outbursts in FU Ori-type systems. The high power of such outbursts causes dramatic changes in the physical…
Dancing on the Grain: Variety of CO and its isotopologue fluxes as a result of surface chemistry and T Tauri disk properties
L. Zwicky, T. Molyarova, Ã. Kóspál +1
At the moment, one of the main ways to infer the disk mass is to use a combination of CO isotopologue line observations. A number of theoretical studies have concluded that CO must…
