Finding New Debris Discs at Sub-millimetre Wavelengths

Mark Booth, Patricia Luppe, Sebastian Marino +9

Debris discs reveal the architectures and dynamical histories of planetary systems. Sub-millimetre observations trace large dust grains within debris discs, revealing their bulk pr…

HD 143811 AB b: A Directly Imaged Planet Orbiting a Spectroscopic Binary in Sco-Cen

Nathalie K. Jones, Jason J. Wang, Eric L. Nielsen +51

We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD…

Characterization of the Host Binary of the Directly Imaged Exoplanet HD 143811 AB b

Anne E. Peck, William Roberson, Eric L. Nielsen +50

HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the S…

High Resolution ALMA Data of the Fomalhaut Debris Disk Confirms Apsidal Width Variation

Jay S. Chittidi, Meredith A. MacGregor, Joshua Bennett Lovell +11

We present long-baseline observations of the Fomalhaut outer debris disk at 223 GHz (1.3 mm) from ALMA Cycle 5, which we use along with archival short-baseline observations to prod…

The Disks In Scorpius-Centaurus Survey (DISCS) I: Four Newly-Resolved Debris Disks in Polarized Intensity Light

Justin Hom, Thomas M. Esposito, Katie A. Crotts +8

The presence of infrared excesses around stars directly correlates to spatially-resolved imaging detections of circumstellar disks at both mm and optical/near-infrared wavelengths.…

Debris disks around M dwarfs: The Herschel DEBRIS survey

Jean-Francois Lestrade, Brenda C. Matthews, Grant M. Kennedy +7

The Herschel open-time key program Disc Emission via a Bias-free Reconnaissance in the Infrared and Sub-millimeter (DEBRIS) is an unbiased survey of the nearest ~100 stars for each…
