Gas dynamics around dust asymmetries in turbulent disks
Lizxandra Flores-Rivera, Natascha Manger, Michiel Lambrechts +4
High-resolution ALMA observations have revealed asymmetric dust crescents in several protoplanetary disks, suggesting efficient dust trapping mechanisms potentially linked to gas v…
Exoplanet formation inference using conditional invertible neural networks
Remo Burn, Victor F. Ksoll, Hubert Klahr +1
The interpretation of the origin of observed exoplanets is usually done only qualitatively due to uncertainties of key parameters in planet formation models. To allow a quantitativ…
Multidimensional half-moment multigroup radiative transfer. Improving moment-based thermal models of circumstellar disks
David Melon Fuksman, Mario Flock, Hubert Klahr +2
Common moment-based radiative transfer methods, such as flux-limited diffusion (FLD) and the M1 closure, suffer from artificial interactions between crossing beams. In protoplaneta…
The Origins & Reservoirs of Exocomets
Michele Bannister, Susanne Pfalzner, Tim Pearce +11
Small bodies exist in distinct populations within their planetary systems. These reservoir populations hold a range of compositions, which to first order are dependent on formation…
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…
Kinetic Field Theory Applied to Planetesimal Formation I: Freely Streaming Dust Particles
Jiahan Shi, Matthias Bartelmann, Hubert Klahr +1
Planet formation in the solar system was started when the first planetesimals were formed from the gravitational collapse of pebble clouds. Numerical simulations of this process, e…
