Geometry of dust rings in protoplanetary disks: the case of LkCa 15
Yansong Qian, Yanqin Wu
Dust properties in proto-planetary disks shape the pathways for planet formation. Here, we present a method to measure these properties in moderately inclined dust rings. Our metho…

Bouncing Grains Keep Protoplanetary Disks Bright
Yansong Qian, Yanqin Wu
Proto-planetary disks display the so-called size-luminosity relation, where their mm-wavelength fluxes scale linearly with their emitting areas. This suggests that these disks are…

Shadows Wreak Havocs in Transition Disks
Yansong Qian, Yanqin Wu
We demonstrate that shadows cast on a proto-planetary disk can drive it eccentric. Stellar irradiation dominates heating across much of these disks, so an uneven illumination can h…
