Cooling-regulated gas accretion onto gap-opening planets

Ayumu Kuwahara, Michiel Lambrechts, Minghao Zhang +2

Gas accretion onto forming planets controls the final masses of giant planets and provides observable signatures of ongoing formation. How this process depends on the cooling prope…

Volatile depletion in rocky planets as a chemical fingerprint of hybrid accretion

Haiyang S. Wang, Anders Johansen, Ziyan Xu +7

Volatile depletion in rocky planets relative to their host stars is commonplace in both the Solar System and exoplanetary systems, yet the connections between planet formation and…

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…
