Probing the era of giant collisions: millimeter observations of the HD 166191 system
Kadin Worthen, Christine H. Chen, A. Meredith Hughes +5
We present non-simultaneous ALMA band 7 and SMA observations of the HD 166191 disk, which was recently thought to have a collision in its terrestrial planet zone. Both observations…
The influence of tight binaries on proto-planetary disk masses
Kevin Flaherty, Peter Knowlton, Tasan Smith-Gandy +5
Binary systems are a common site of planet formation, despite the destructive effects of the binary on the disk. While surveys of planet forming material have found diminished disk…
Multiwavelength Vertical Structure in the AU Mic Debris Disk: Characterizing the Collisional Cascade
David Vizgan, A. Meredith Hughes, Evan S. Carter +9
Debris disks are scaled-up analogs of the Kuiper Belt in which dust is generated by collisions between planetesimals. In the "collisional cascade" model of debris disks, dust lost…
The first radio spectrum of a rapidly rotating A-type star
Jacob Aaron White, F. Tapia-Vázquez, A. G. Hughes +9
The radio spectra of main-sequence stars remain largely unconstrained due to the lack of observational data to inform stellar atmosphere models. As such, the dominant emission mech…
Dust Populations in the Iconic Vega Planetary System Resolved by ALMA
Luca Matrà, William R. F. Dent, David J. Wilner +9
The Vega planetary system hosts the archetype of extrasolar Kuiper belts, and is rich in dust from the sub-au region out to 100's of au, suggesting intense dynamical activity. We p…
Radial Surface Density Profiles of Gas and Dust in the Debris Disk around 49 Ceti
A. M. Hughes, J. Lieman-Sifry, K. M. Flaherty +9
We present ~0.4 resolution images of CO(3-2) and associated continuum emission from the gas-bearing debris disk around the nearby A star 49 Ceti, observed with the Atacama Large Mi…
ALMA Observations of HD141569's Circumstellar Disk
J. A. White, A. C. Boley, A. M. Hughes +5
We present ALMA band 7 (345 GHz) continuum and CO(J = 3-2) observations of the circumstellar disk surrounding HD141569. At an age of about 5 Myr, the disk has a complex morp…
Chemical Imaging of the CO Snow Line in the HD 163296 Disk
Chunhua Qi, Karin I. Oberg, Sean M. Andrews +5
The condensation fronts (snow lines) of H2O, CO and other abundant volatiles in the midplane of a protoplanetary disk affect several aspects of planet formation. Locating the CO sn…
