Emergent Spinning and Orbital Motion in Clustered Wind-Assisted Flyers. [PDF]
Adv Sci (Weinh)Inspired by natural snowflake geometries, paper‐cut flyers exhibit geometry‐defined spinning and orbital motions during cluster formation in a wind tunnel. Collective flights of multiple paperflakes reveal dynamic clustering, fragmentation, and continuously evolving spin behaviors.

On the interaction between embedded planets and the corotation region of protoplanetary discs [PDF]
, 2015 PhDDisc material in the corotation region librates with respect to low-mass planets on horseshoe trajectories. The exchange of angular momentum associated with this libration gives rise to the non-linear corotation torque (the horseshoe drag).
