[Abridged] Most well-resolved disks observed with ALMA show signs of dust traps. These dust traps set the chemical composition of the planet forming material in these disks, as the dust grains with their icy mantles are trapped at specific radii and

Disc population synthesis:Decrease in the solid mass reservoir through pebble drift

Autor: J. Appelgren, M. Lambrechts, N. van der Marel

Publikováno v: Appelgren, J, Lambrechts, M & van der Marel, N 2023, ' Disc population synthesis : Decrease in the solid mass reservoir through pebble drift ', Astronomy & Astrophysics, vol. 673, A139 . https://doi.org/10.1051/0004-6361/202245252

Surveys of star-forming regions reveal that the dust mass of protoplanetary discs decreases by several orders of magnitude on a timescale of a few million years. This decrease in the mass budget of solids is likely due to the gas-drag-induced radial

In recent years, high-angular-resolution observations of the dust and gas in circumstellar discs have revealed a variety of morphologies, naturally triggering the question of whether these substructures are driven by forming planets. While it remains
