The JCMT Gould Belt Survey: A First Look at Dense Cores in Orion B
H. Kirk, J. Di Francesco, D. Johnstone +54
We present a first look at the SCUBA-2 observations of three sub-regions of the Orion B molecular cloud: LDN 1622, NGC 2023/2024, and NGC 2068/2071, from the JCMT Gould Belt Legacy…
IR-excesses around nearby Lambda Boo stars are caused by debris disks rather than ISM bow waves
Zachary H Draper, Brenda C Matthews, Grant M Kennedy +3
Lambda Boo stars are predominately A-type stars with solar abundant C, N, O, and S, but up to 2 dex underabundances of refractory elements. The stars' unusual surface abundances co…
Direct imaging of an asymmetric debris disk in the HD 106906 planetary system
Paul G. Kalas, Abhijith Rajan, Jason J. Wang +53
We present the first scattered light detections of the HD 106906 debris disk using Gemini/GPI in the infrared and HST/ACS in the optical. HD 106906 is a 13 Myr old F5V star in the…
The AU Mic Debris Disk: far-infrared and submillimeter resolved imaging
Brenda C. Matthews, Grant Kennedy, Bruce Sibthorpe +20
We present far-infrared and submillimeter maps from the Herschel Space Observatory and the James Clerk Maxwell Telescope of the debris disk host star AU Microscopii. Disk emission…
Young Stellar Objects in the Gould Belt
Michael M. Dunham, Lori E. Allen, Neal J. Evans +14
We present the full catalog of Young Stellar Objects (YSOs) identified in the 18 molecular clouds surveyed by the Spitzer Space Telescope "cores to disks" (c2d) and "Gould Belt" (G…
ALMA Observations of the Largest Proto-Planetary Disk in the Orion Nebula, 114-426: A CO Silhouette
John Bally, Rita K. Mann, Josh Eisner +7
We present ALMA observations of the largest protoplanetary disk in the Orion Nebula, 114-426. Detectable 345 GHz (856 micron) dust continuum is produced only in the 350 AU central…
