Weak Turbulence in the HD 163296 Protoplanetary Disk Revealed by ALMA CO Observations
Kevin M. Flaherty, A. Meredith Hughes, Katherine A. Rosenfeld +5
Turbulence can transport angular momentum in protoplanetary disks and influence the growth and evolution of planets. With spatially and spectrally resolved molecular emission line…
A Combined Spitzer and Herschel Infrared Study of Gas and Dust in the Circumbinary Disk Orbiting V4046 Sgr
Valerie A. Rapson, Benjamin Sargent, G. Germano Sacco +6
We present results from a spectroscopic Spitzer and Herschel mid-to-far-infrared study of the circumbinary disk orbiting the evolved (age ~12-23 Myr) close binary T Tauri system V4…
Resolved Multifrequency Radio Observations of GG Tau
Sean M. Andrews, Claire J. Chandler, Andrea Isella +20
We present sub-arcsecond resolution observations of continuum emission associated with the GG Tau quadruple star system at wavelengths of 1.3, 2.8, 7.3, and 50 mm. These data confi…
Fast Radial Flows in Transition Disk Holes
Katherine A. Rosenfeld, Eugene Chiang, Sean M. Andrews
Protoplanetary "transition" disks have large, mass-depleted central cavities, yet also deliver gas onto their host stars at rates comparable to disks without holes. The paradox of…
The Structure of the Evolved Circumbinary Disk around V4046 Sgr
Katherine A. Rosenfeld, Sean M. Andrews, David J. Wilner +2
We present sensitive, sub-arcsecond resolution Submillimeter Array observations of the protoplanetary disk around the nearby, pre-main sequence spectroscopic binary V4046 Sgr. We r…
An azimuthal asymmetry in the LkHa 330 disk
Andrea Isella, Laura M. Pe'rez, John M. Carpenter +3
Theory predicts that giant planets and low mass stellar companions shape circumstellar disks by opening annular gaps in the gas and dust spatial distribution. For more than a decad…
A Spatially Resolved Vertical Temperature Gradient in the HD 163296 Disk
Katherine A. Rosenfeld, Sean M. Andrews, A. Meredith Hughes +2
We analyze sensitive, sub-arcsecond resolution ALMA Science Verification observations of CO emission lines in the protoplanetary disk hosted by the young, isolated Ae star HD 16329…
The Mass Dependence Between Protoplanetary Disks and their Stellar Hosts
Sean M. Andrews, Katherine A. Rosenfeld, Adam L. Kraus +1
We present a substantial extension of the mm-wave continuum photometry catalog for Taurus circumstellar dust disks. Combining new Submillimeter Array data with measurements in the…
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…
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…
