The Streaming Instability in 3D: Conditions for Strong Clumping
Jeonghoon Lim, Jacob B. Simon, Rixin Li +3
The streaming instability (SI) is a leading mechanism for planetesimal formation, driving the aerodynamic concentration of solids in protoplanetary disks. The SI triggers strong cl…
On the Mass Budget Problem of Protoplanetary Disks: Streaming Instability and Optically Thick Emission
Daniel Godines, Wladimir Lyra, Luca Ricci +4
Statistical studies of protoplanetary disks and exoplanet populations often exhibit a "missing mass" problem, where observed dust masses in (sub-)millimeter surveys are significant…
Bridging Unstratified and Stratified Simulations of the Streaming Instability for Grains
Jeonghoon Lim, Stanley A. Baronett, Jacob B. Simon +4
The streaming instability (SI), driven by aerodynamic coupling between solids and the gas under a global radial pressure gradient, concentrates solids and facilitates planetesimal…
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…
Planets and planetesimals at cosmic dawn: Vortices as planetary nurseries
Linn E. J. Eriksson, Shyam Menon, Daniel Carrera +2
Low-mass, metal-enriched stars were likely present as early as cosmic dawn. In this work, we investigate whether these stars could have hosted planets in their protoplanetary disks…
