Close-in faint companions mimicking interferometric hot exozodiacal dust observations
Katsiaryna Tsishchankava, Florian Kirchschlager, Anton Krieger +2
Context: Interferometric observations of various nearby main-sequence stars show an unexpected infrared excess, raising the question of its origin. The two dominant interpretations…

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…

Monte Carlo post-processing for radiation hydro simulations of accreting planets in protoplanetary disks
Anton Krieger, Hubert Klahr, Julio David Melon Fuksman +1
This paper is part of a series investigating the observational appearance of planets accreting from their nascent protoplanetary disk (PPD). We evaluate the differences between gas…
