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…
The structure of accreted stellar streams
Yansong Qian, Yumna Arshad, Jo Bovy
Many of the Milky Way's globular clusters are likely accreted from satellite galaxies that have long since merged with the Milky Way. When these globular clusters are susceptible t…
Super-Earths and sub-Neptunes are Insensitive to Stellar Metallicity
Taylor Kutra, Yanqin Wu, Yansong Qian
Kepler planets (including super-Earths and sub-Neptunes, from 1 to 4 Earth radii) are likely formed before the gaseous proto-planetary disks have dissipated, as are the Jovian plan…
