Meso-scale Instability Triggered by Dust Feedback in Dusty Rings: Origin and Observational Implications
Pinghui Huang, Hui Li, Andrea Isella +3
High spatial resolution observations of protoplanetary disks (PPDs) by ALMA have revealed many details that are providing interesting constraints on the disk physics as well as dus…
The Observability Of Vortex-Driven Spiral Arms In Protoplanetary Disk: Basic Spiral Properties
Pinghui Huang, Ruobing Dong, Hui Li +2
Some circumstellar disks are observed to show prominent spiral arms in infrared scattered light or (sub-)millimeter dust continuum. The spirals might be formed from self-gravity, s…
New constraints on the dust and gas distribution in the LkCa 15 disk from ALMA
Sheng Jin, Andrea Isella, Pinghui Huang +3
We search a large parameter space of the LkCa 15's disk density profile to fit its observed radial intensity profile of CO (J = 3-2) obtained from ALMA. The best-fit model w…
Identifying Anticyclonic Vortex Features Produced by the Rossby Wave Instability in Protoplanetary Disks
Pinghui Huang, Andrea Isella, Hui Li +2
Several nearby protoplanetary disks have been observed to display large scale crescents in the (sub)millimeter dust continuum emission. One interpretation is that these structures…
