The Radial Profile of Dust Grain Size in the Protoplanetary Disk of DS Tau
Dafa Li, Yao Liu, Hongchi Wang +2
How do dust grains in protoplanetary disks overcome rapid radial drift and grow from micron size particles to planets is not well understood. The key is to search for evidence of d…
On the underestimation of dust mass in protoplanetary disks: Effects of disk structure and dust properties
Yao Liu, Hendrik Linz, Min Fang +6
The total amount of dust grains in protoplanetary disks is one of the key properties that characterize the potential for planet formation. With (sub-)millimeter flux measurements,…
Evolution of Galaxy Types and HI Gas in Hickson Compact Groups
Yao Liu, Ming Zhu
Compact groups have high galaxy densities and low velocity dispersions, and their group members have experienced numerous and frequent interactions during their lifetimes. They pro…
Millimeter Gap Contrast as a Probe for Turbulence Level in Protoplanetary Disks
Yao Liu, Gesa H. -M. Bertrang, Mario Flock +7
Turbulent motions are believed to regulate angular momentum transport and influence dust evolution in protoplanetary disks. Measuring the strength of turbulence is challenging thro…
