A Comparative Study of the Streaming Instability: Unstratified Models with Marginally Coupled Grains
Stanley A. Baronett, Wladimir Lyra, Hossam Aly +19
The streaming instability is a leading mechanism for concentrating solids and initiating planetesimal formation in protoplanetary disks. Although numerous studies have explored its…
Conditions for planetesimal formation via the streaming instability persist under turbulence driven by magnetorotational instability
Linn E. J. Eriksson, Ziyan Xu, Jeonghoon Lim +3
Strong dust clumping by streaming instability (SI) is the leading proposed mechanism for forming planetesimals, the building blocks of terrestrial planets and giant-planet cores. T…
Positive Feedback II: How Dust Coagulation inside Vortices Can Form Planetesimals at Low Metallicity
Daniel Carrera, Linn E. J. Eriksson, Jeonghoon Lim +2
The origin of planetesimals (100 km planet building blocks) has confounded astronomers for decades, as numerous growth barriers appear to impede their formation. In a recent…
Positive Feedback: How a Synergy Between the Streaming Instability and Dust Coagulation Forms Planetesimals
Daniel Carrera, Jeonghoon Lim, Linn E. J. Eriksson +2
One of the most important open questions in planet formation is how dust grains in a protoplanetary disk manage to overcome growth barriers and form the 100km planet building…
