Azimuthal Dust Polarization from Aerodynamically Aligned Grains as Evidence for the Streaming Instability in Protoplanetary Disks
Zhe-Yu Daniel Lin, Jeonghoon Lim, Jacob B. Simon +8
(Sub)millimeter dust polarization in protoplanetary disks has revealed the presence of large (~ 100 um) dust grains that are aligned along their long axis following the azimuthal d…
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…
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…
Probing Conditions for Strong Clumping by the Streaming Instability: Small Dust Grains and Low Dust-to-gas Density Ratio
Jeonghoon Lim, Jacob B. Simon, Rixin Li +5
The streaming instability (SI) is a leading mechanism for concentrating solid particles into regions dense enough to form planetesimals. Its efficiency in clumping particles depend…
