Spiral formation caused by late infall onto protoplanetary disks

L. -A. Hühn, C. N. Kimmig, C. P. Dullemond

The classical picture that planet formation occurs in protoplanetary disks that are isolated from their environment is undergoing a major shift toward a more connected picture. An…

Emergence of streamers in simulations of late infall

L. -A. Hühn, C. P. Dullemond

Growing observational evidence suggests that Class II protoplanetary disks may undergo substantial interactions with their environment in the form of late infall. This mass inflow…

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…

Late accretion offers pathway to misaligned disk around the planet-hosting IRAS 04125+2902

L. -A. Hühn, H. -C. Jiang, C. P. Dullemond

We present a 3D hydrodynamical simulation of the accretion of a gas cloudlet onto the IRAS 04125+2902 binary system, where the 3-Myr primary hosts a transiting planet. We demonstra…

Planetesimal formation via the streaming instability in simulations of infall dominated young disks

L. -A. Hühn, C. P. Dullemond, U. Lebreuilly +7

Protoplanetary disks naturally emerge during protostellar core-collapse. In their early evolutionary stages, infalling material dominates their dynamical evolution. In the context…
