Spiral excitation in protoplanetary disks through gap-edge illumination: Distinctive kinematic signatures in CO isotopologues
Dhruv Muley, León-Alexander Hühn, Haochang Jiang +1
High-resolution, near-infrared observations have revealed prominent, two-armed spirals in a multitude of systems, such as MWC~758, SAO~206462, and V1247~Ori. Alongside the classica…
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…
Can gap-edge illumination excite spirals in protoplanetary disks? Three-temperature radiation hydrodynamics and NIR image modelling
Dhruv Muley, Julio David Melon Fuksman, Hubert Klahr
The advent of high-resolution, near-infrared instruments such as VLT/SPHERE and Gemini/GPI has helped uncover a wealth of substructure in planet-forming disks, including large, pro…
Three-temperature radiation hydrodynamics with PLUTO: Thermal and kinematic signatures of accreting protoplanets
Dhruv Muley, Julio David Melon Fuksman, Hubert Klahr
In circumstellar disks around young stars, the gravitational influence of nascent planets produces telltale patterns in density, temperature, and kinematics. To better understand t…
