Dust transport in envelopes of disk-embedded planets: II. Fully convective envelopes
Ayumu Kuwahara, Michiel Lambrechts
We perform 3D multifluid simulations of gas and dust to quantify how convection reshapes the spatial distribution of dust grains inside the envelopes of disk-embedded planets. Buil…
Dust transport in envelopes of disk-embedded planets: I. Convectively stable envelopes
Ayumu Kuwahara, Michiel Lambrechts
Planets embedded in protoplanetary disks accrete solids through their gaseous envelopes. The spatial distribution of these dust particles inside the envelopes of disk-embedded plan…
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…
A break in planet occurrence near the pebble isolation mass should be observable by the Roman microlensing survey
Claudia Danti, Michiel Lambrechts, Hannah Diamond-Lowe
Microlensing detections are uniquely well-suited to probing the population of planets outside the water iceline, down to planetary masses comparable to the Earth. Here, we perform…
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…
From planetesimals to planets with N-body simulations in the giant-planet formation region
Sebastian Lorek, Michiel Lambrechts
The cores of wide-orbit giant planets can form via pebble accretion if large planetesimals form in the outer regions of protoplanetary discs at sufficiently early times. Streaming…
