Spiral arms in scattered light images of protoplanetary discs: Are they the signposts of planets?
Attila Juhasz, Myriam Benisty, Adriana Pohl +3
One of the striking discoveries of protoplanetary disc research in recent years are the spiral arms seen in several transitional discs in polarised scattered light. An interesting…
Can dust coagulation trigger streaming instability?
Joanna Drazkowska, Cornelis P. Dullemond
Streaming instability can be a very efficient way of overcoming growth and drift barriers to planetesimal formation. However, it was shown that strong clumping, which leads to plan…
Planet-vortex interaction:How a vortex can shepherd a planetary embryo
S. Ataiee, C. P. Dullemond, W. Kley +2
Context: Anticyclonic vortices are considered as a favourable places for trapping dust and forming planetary embryos. On the other hand, they are massive blobs that can interact gr…
A critical analysis of shock models for chondrule formation
Sebastian M. Stammler, Cornelis P. Dullemond
In recent years many models of chondrule formation have been proposed. One of those models is the processing of dust in shock waves in protoplanetary disks. In this model, the dust…
Modeling dust growth in protoplanetary disks: The breakthrough case
Joanna Drazkowska, Fredrik Windmark, Cornelis P. Dullemond
Simple toy models are often not sufficient to cover the complexity of the dust coagulation process, and a number of numerical approaches are therefore used, among which integration…
Millimetre spectral indices of transition disks and their relation to the cavity radius
P. Pinilla, M. Benisty, T. Birnstiel +7
Transition disks are protoplanetary disks with inner depleted dust cavities and excellent candidates to investigate the dust evolution under the existence of a pressure bump. A pre…
