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 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…
Feasibility of interferometric observations and characterization of planet-induced structures at sub au to au scales in protoplanetary disks
Lukas Hildebrandt, Anton Krieger, Hubert Klahr +3
Interferometric observations of protoplanetary disks by VLTI and ALMA have greatly improved our understanding of the detailed structure of these planetary birthplaces. These observ…
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…
Shaping the CO snowline in protoplanetary disks
S. Gavino, J. Kobus, A. Dutrey +4
Characterizing the dust thermal structure in protoplanetary disks is a fundamental task as the dust surface temperature can affect both the planetary formation and the chemical evo…
The potential of VLTI observations for the study of circumstellar disk variability
A. Bensberg, J. Kobus, S. Wolf
Context. A characteristic feature of young stellar objects is their variability, which is caused by a variety of different physical processes. High-resolution interferometric obser…
Radiative transfer simulations for in-situ particle size diagnostic in reactive, particle growing plasmas
Julia Kobus, Andreas Petersen, Franko Greiner +1
When considering particles produced in reactive plasmas, their basic properties, such as refractive index and grain size often need to be known. They can be constrained both ex-sit…
Impact of Size-dependent Grain Temperature on Gas-Grain Chemistry in Protoplanetary Disks: the case of low mass star disks
S. Gavino, A. Dutrey, V. Wakelam +7
Grain surface chemistry is key to the composition of protoplanetary disks around young stars. The temperature of grains depends on their size. We evaluate the impact of this temper…
Interferometric study on the temporal variability of the brightness distributions of protoplanetary disks
J. Kobus, S. Wolf, T. Ratzka +1
Multi-epoch observations have revealed the variability of pre-main sequence stars and/or their environment. Moreover, structures in orbital motion around the central star, resultin…
The potential of combining MATISSE and ALMA observations: Constraining the structure of the innermost region in protoplanetary discs
Julia Kobus, Sebastian Wolf, Robert Brunngräber
In order to study the initial conditions of planet formation, it is crucial to obtain spatially resolved multi-wavelength observations of the innermost region of protoplanetary dis…
