Observations of protoplanetary disk structures

SM Andrews - Annual Review of Astronomy and Astrophysics, 2020 - annualreviews.org
The disks that orbit young stars are the essential conduits and reservoirs of material for star
and planet formation. Their structures, meaning the spatial variations of the disk physical …

Contemporary formation of early Solar System planetesimals at two distinct radial locations

A Morbidelli, K Baillie, K Batygin, S Charnoz… - Nature …, 2022 - nature.com
The formation of planetesimals is expected to occur via particle-gas instabilities that
concentrate dust into self-gravitating clumps,–. Triggering these instabilities requires the …

Planetesimal rings as the cause of the Solar System's planetary architecture

Thresholds for particle clumping by the streaming instability

R Li, AN Youdin - The Astrophysical Journal, 2021 - iopscience.iop.org
The streaming instability (SI) is a mechanism to aerodynamically concentrate solids in
protoplanetary disks and trigger the formation of planetesimals. The SI produces strong …
