Exploring the conditions for forming planetesimals by the streaming instability and planetary systems by pebble accretion
Anders Johansen, Wladimir Lyra
The streaming instability and pebble accretion are two physical mechanisms with demonstrated potentials to drive, respectively, the formation of planetesimals and the growth of pla…
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…
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…
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…
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…
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…
