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…
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…
The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase
Feng Long, Ilaria Pascucci, Adrien Houge +20
We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16262756.1B (hereafter J0446B), an old (34 Myr) M4.5 star but with hints of ongoing accretion. The sp…
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…
Thresholds for Particle Clumping by the Streaming Instability
Rixin Li, Andrew Youdin
The streaming instability (SI) is a mechanism to aerodynamically concentrate solids in protoplanetary disks and trigger the formation of planetesimals. The SI produces strong parti…
