Probing Dust in the MWC 480 Disk from Millimeter to Centimeter Wavelengths
Yangfan Shi, Feng Long, Enrique Macías +12
We present deep, high-resolution (100 mas) Karl G. Jansky Very Large Array (VLA) Ka-band (9.1 mm) observations of the disk around MWC 480, and infer dust properties through a…
Discovery of H Emission from a Protoplanet Candidate Around the Young Star 2MASS J16120668-3010270 with MagAO-X
Jialin Li, Laird M. Close, Feng Long +32
2MASS J16120668-3010270 (hereafter 2MJ1612) is a young M0 star that hosts a protoplanetary disk in the Upper Scorpious star-forming region. Recent ALMA observations of 2MJ1612 show…
Small and Large Dust Cavities in Disks around mid-M Stars in Taurus
Yangfan Shi, Feng Long, Gregory J. Herczeg +10
High-angular resolution imaging by ALMA has revealed the near-universality and diversity of substructures in protoplanetary disks. However, disks around M-type pre-main-sequence st…
Dual-Band Observations of the Asymmetric Ring around CIDA 9A: Dead or Alive?
Daniel Harsono, Feng Long, Paola Pinilla +9
While the most exciting explanation of the observed dust asymmetries in protoplanetary disks is the presence of protoplanets, other mechanisms can also form the dust features. This…
