Accretion across scales: streamers, surface-layer transport, and rapid replenishment in young protoplanetary discs

Christian Granzow Holm, Michiel Lambrechts, Michael Kuffmeier +3

Protoplanetary discs evolve around newly-formed stars through an interplay of infall from surrounding turbulent cloud material, accretion towards the young star, and outflow driven…

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…

The evolution of the flux-size relationship in protoplanetary discs by viscous evolution and radial pebble drift

Johan Appelgren, Anders Johansen, Michiel Lambrechts +4

In this paper we study the evolution of radiative fluxes, flux radii and observable dust masses in protoplanetary discs, in order to understand how these depend on the angular mome…

UV-processing of icy pebbles in the outer parts of VSI-turbulent disks

Lizxandra Flores-Rivera, Michiel Lambrechts, Sacha Gavino +4

Icy dust particles emerge in star-forming clouds and are subsequently incorporated in protoplanetary disks, where they coagulate into larger pebbles up to mm in size. In the disk m…

Comment on "Did the terrestrial planets of the Solar System form by pebble accretion?"

Anders Johansen, Peter Olson, Zachary Sharp

Morbidelli, Kleine & Nimmo (2024) (MKN) recently published a critical analysis on whether the terrestrial planets in the Solar System formed by rapid pebble accretion or by the cla…
