Multiple Rings of Millimeter Dust Emission in the HD 15115 Debris Disk
Meredith A. MacGregor, Alycia J. Weinberger, Erika R. Nesvold +8
We present observations of the HD 15115 debris disk from ALMA at 1.3 mm that capture this intriguing system with the highest resolution ( or AU) at mil…
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…
New Parallaxes for the Upper Scorpius OB Association
Jessica Donaldson, Alycia Weinberger, Jonathan Gagné +2
Upper Scorpius is a subgroup of the nearest OB association, Scorpius--Centaurus. Its young age makes it an important association to study star and planet formation. We present para…
Optical Coronagraphic Spectroscopy of AU Mic: Evidence of Time Variable Colors?
Jamie R. Lomax, John P. Wisniewski, Aki Roberge +4
We present coronagraphic long slit spectra of AU Mic's debris disk taken with the STIS instrument aboard the Hubble Space Telescope (HST). Our spectra are the first spatially resol…
Exocometary gas in the HD 181327 debris ring
S. Marino, L. Matra, C. Stark +14
An increasing number of observations have shown that gaseous debris discs are not an exception. However, until now we only knew of cases around A stars. Here we present the first d…
Herschel PACS Observations and Modeling of Debris Disks in the Tucana-Horologium Association
J. K. Donaldson, A. Roberge, C. H. Chen +9
We present Herschel PACS photometry of seventeen B- to M-type stars in the 30 Myr-old Tucana-Horologium Association. This work is part of the Herschel Open Time Key Programme "Gas…
