ALMA observations of the debris disk around the young Solar Analog HD 107146
L. Ricci, J. M. Carpenter, B. Fu +3
We present ALMA continuum observations at a wavelength of 1.25 mm of the debris disk surrounding the 100 Myr old solar analog HD 107146. The continuum emission extends from…
ALMA observations of a misaligned binary protoplanetary disk system in Orion
Jonathan P. Williams, Rita K. Mann, James Di Francesco +6
We present ALMA observations of a wide binary system in Orion, with projected separation 440 AU, in which we detect submillimeter emission from the protoplanetary disks around each…
Spatially Resolved Magnetic Field Structure in the Disk of a T Tauri Star
Ian W. Stephens, Leslie W. Looney, Woojin Kwon +6
Magnetic fields in accretion disks play a dominant role during the star formation process but have hitherto been observationally poorly constrained. Field strengths have been infer…
A CO survey in planet-forming disks: characterizing the gas content in the epoch of planet formation
A. S. Hales, I. De Gregorio-Monsalvo, B. Montesinos +13
We carried out a 12CO(3-2) survey of 52 southern stars with a wide range of IR excesses (LIR/L*) using the single dish telescopes APEX and ASTE. The main aims were (1) to character…
Molecular Gas Clumps from the Destruction of Icy Bodies in the Pictoris Debris Disk
W. R. F. Dent, M. C. Wyatt, A. Roberge +11
Many stars are surrounded by disks of dusty debris formed in the collisions of asteroids, comets and dwarf planets. But is gas also released in such events? Observations at submm w…
ALMA Observations of the Orion Proplyds
Rita K. Mann, James Di Francesco, Doug Johnstone +6
We present ALMA observations of protoplanetary disks ("proplyds") in the Orion Nebula Cluster. We imaged 5 individual fields at 856um containing 22 HST-identified proplyds and dete…
