ALMA Detection of Extended Millimeter Halos in the HD 32297 and HD 61005 Debris Disks
Meredith A. MacGregor, Alycia J. Weinberger, A. Meredith Hughes +7
We present ALMA 1.3 mm (230 GHz) observations of the HD 32297 and HD 61005 debris disks, two of the most iconic debris disks due to their dramatic swept-back wings seen in scattere…
Deep ALMA Search for CO Gas in the HD 95086 Debris Disc
Mark Booth, Luca Matrà, Kate Y. L. Su +7
One of the defining properties of debris discs compared to protoplanetary discs used to be their lack of gas, yet small amounts of gas have been found around an increasing number o…
Science Impacts of the SPHEREx All-Sky Optical to Near-Infrared Spectral Survey II: Report of a Community Workshop on the Scientific Synergies Between the SPHEREx Survey and Other Astronomy Observatories
Olivier Doré, Michael W. Werner, Matthew L. N. Ashby +60
SPHEREx is a proposed NASA MIDEX mission selected for Phase A study. SPHEREx would carry out the first all-sky spectral survey in the near infrared. At the end of its two-year miss…
Detection of a Millimeter Flare From Proxima Centauri
Meredith A. MacGregor, Alycia J. Weinberger, David J. Wilner +2
We present new analyses of ALMA 12-m and ACA observations at 233 GHz (1.3 mm) of the Proxima Centauri system with sensitivities of 9.5 and 47 Jy beam, respectively, taken…
Resolved Millimeter Observations of the HR 8799 Debris Disk
David J. Wilner, Meredith A. MacGregor, Sean M. Andrews +3
We present 1.3 millimeter observations of the debris disk surrounding the HR 8799 multi-planet system from the Submillimeter Array to complement archival ALMA observations that spa…
