Millimeter Emission Structure in the first ALMA Image of the AU Mic Debris Disk
Meredith A. MacGregor, David J. Wilner, Katherine A. Rosenfeld +9
We present 1.3 millimeter ALMA Cycle 0 observations of the edge-on debris disk around the nearby, ~10 Myr-old, M-type star AU Mic. These observations obtain 0.6 arcsec (6 AU) resol…
A Disk-based Dynamical Mass Estimate for the Young Binary V4046 Sgr
Katherine A. Rosenfeld, Sean M. Andrews, David J. Wilner +1
We present sensitive, arcsecond-resolution Submillimeter Array observations of the 12CO J=2-1 line emission from the circumstellar disk orbiting the double-lined spectroscopic bina…
Matryoshka Holes: Nested Emission Rings in the Transitional Disk Oph IRS 48
Joanna M. Brown, Katherine A. Rosenfeld, Sean M. Andrews +2
The processes that form transition disks - disks with depleted inner regions - are not well understood; possible scenarios include planet formation, grain growth and photoevaporati…
Kinematics of the CO Gas in the Inner Regions of the TW Hya Disk
Katherine A. Rosenfeld, Chunhua Qi, Sean M. Andrews +7
We present a detailed analysis of the spatially and spectrally resolved 12CO J=2-1 and J=3-2 emission lines from the TW Hya circumstellar disk, based on science verification data f…
