The Structure of the DoAr 25 Circumstellar Disk
Sean M. Andrews, A. M. Hughes, D. J. Wilner +1
We present high spatial resolution (< 0.3" = 40$ AU) Submillimeter Array observations of the 865 micron continuum emission from the circumstellar disk around the young star DoAr 25…
A Resolved Molecular Gas Disk around the Nearby A Star 49 Ceti
A. M. Hughes, D. J. Wilner, I. Kamp +1
The A star 49 Ceti, at a distance of 61 pc, is unusual in retaining a substantial quantity of molecular gas while exhibiting dust properties similar to those of a debris disk. We p…
Proplyds and Massive Disks in the Orion Nebula Cluster Imaged with CARMA and SMA
J. A. Eisner, R. L. Plambeck, John M. Carpenter +3
[Abridged] We imaged a 2' x 2' region of the Orion Nebula cluster in 1.3 mm wavelength continuum emission with the recently commissioned Combined Array for Research in Millimeter A…
Gas and Dust Emission at the Outer Edge of Protoplanetary Disks
A. M. Hughes, D. J. Wilner, C. Qi +1
We investigate the apparent discrepancy between gas and dust outer radii derived from millimeter observations of protoplanetary disks. Using 230 and 345 GHz continuum and CO J=3-2…
