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…
In-Situ Formation of the Cold Classical Kuiper Belt
Rixin Li, Eugene Chiang
Cold Classical Kuiper belt objects (CCKBOs) are considered first-generation planetesimals that formed 42-47 au from the Sun and remained untouched since. Formation is thought to pr…
On the Evolution of Disk-Embedded Binaries: Framing Local Models in Global Context
Philip Kirkeberg, Rixin Li, Martin E. Pessah
The disks of Active Galactic Nuclei (AGN) have in recent years been recognized as possible sites for gravitational wave sources, leading to a series of numerical studies on the evo…
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…
Circumplanetary Disks are Rare around Planets at Large Orbital Radii: A Parameter Survey of Flow Morphology around Giant Planets
Sabina Sagynbayeva, Rixin Li, Aleksandra Kuznetsova +3
We investigate how the formation and structure of circumplanetary disks (CPDs) varies with planet mass and protoplanetary disk aspect ratio. Using static mesh refinement and a near…
The Resonant Remains of Broken Chains from Major and Minor Mergers
Rixin Li, Eugene Chiang, Nick Choksi +1
TESS and Kepler have revealed that practically all close-in sub-Neptunes form in mean-motion resonant chains, most of which unravel on timescales of 100 Myr. Using N-body integrati…
