Planetesimal formation facilitated by streaming instability in weak pressure bumps

Magnus S. Sørensen-Taylor, Anders Johansen, Troels Haugbølle

Planetesimal formation via the streaming instability of small pebbles in protoplanetary discs requires enhanced solid concentrations relative to the solar metallicity, $Z\simeq 0.0…

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…

Fast formation of large ice pebbles after FU Orionis outbursts

Katrin Ros, Anders Johansen

During their formation, nascent planetary systems are subject to FU Orionis outbursts that heat a substantial part of the disc. This causes water ice in the affected part of the di…

How the presence of a giant planet affects the outcome of terrestrial planet formation simulations

Zhihui Kong, Anders Johansen, Michiel Lambrechts +2

The architecture and masses of planetary systems in the habitable zone could be strongly influenced by outer giant planets, if present. We investigate here the impact of outer gian…

Vapor equilibrium models of accreting rocky planets demonstrate direct core growth by pebble accretion

Marie-Luise Steinmeyer, Anders Johansen

The gaseous envelope of an accreting rocky planet becomes hot enough to sublimate silicates and other refractory minerals. For this work, we studied the effect of the resulting env…

Thermal processing of primordial pebbles in evolving protoplanetary disks

Maria Jose Colmenares, Michiel Lambrechts, Elishevah van Kooten +1

During protoplanetary disk formation, dust grains located in the outer disk retain their pristine icy composition, while solids in the inner stellar-heated disk undergo volatile lo…

Formation of flattened planetesimals by gravitational collapse of rotating pebble clouds

Sebastian Lorek, Anders Johansen

Planetesimals are believed to form by the gravitational collapse of aerodynamically concentrated clumps of pebbles. Many properties of the objects in the cold classical Kuiper belt…

Forming Giant Planets Around Late-M Dwarfs: Pebble Accretion and Planet-Planet Collision

Mengrui Pan, Beibei Liu, Anders Johansen +6

We propose a pebble-driven core accretion scenario to explain the formation of giant planets around the late-M dwarfs of . In order to explore th…

Formation of wide-orbit giant planets in protoplanetary disks with a decreasing pebble flux

Nerea Gurrutxaga, Anders Johansen, Michiel Lambrechts +1

The presence of distant protoplanets may explain the observed gaps in the dust emission of protoplanetary disks. Here, we derive a novel analytical model to describe the temporal d…
