Late-infall-induced formation of giant planets, multi-generational planetesimals, and disk substructures
Haichen Zhao, Tommy Chi Ho Lau, Joanna DrÄ Å¼kowska +2
Late infall can replenish the building materials of planets in protoplanetary disks and dramatically alter their structural evolution. The resulting pressure bumps effectively accu…

A tension between dust and gas radii: the role of substructures and external photoevaporation in protoplanetary disks
Luca Delussu, Rossella Anania, Tilman Birnstiel +5
Protoplanetary disk substructures are thought to play a crucial role in disk evolution and planet formation. Population studies of disks large-sample size surveys show that substru…

Planetesimal formation in a pressure bump induced by infall
Haichen Zhao, Tommy Chi Ho Lau, Tilman Birnstiel +2
Infall of interstellar material is a potential non-planetary origin of pressure bumps in protoplanetary disks. While pressure bumps arising from other mechanisms have been numerica…
