The Gemini Planet Imager view of the HD 32297 debris disk

Gaspard Duchene, Malena Rice, Justin Hom +60

We present new -band scattered light images of the HD 32297 edge-on debris disk obtained with the Gemini Planet Imager (GPI). The disk is detected in total and polarized intensi…

An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light

Bin Ren, Élodie Choquet, Marshall D. Perrin +70

We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…

GPI spectra of HR 8799 c, d, and e from 1.5 to 2.4m with KLIP Forward Modeling

Alexandra Z. Greenbaum, Laurent Pueyo, Jean-Baptiste Ruffio +51

We explore KLIP forward modeling spectral extraction on Gemini Planet Imager coronagraphic data of HR 8799, using PyKLIP and show algorithm stability with varying KLIP parameters.…

Detection of exocometary CO within the 440 Myr-old Fomalhaut belt: a similar CO+CO ice abundance in exocomets and Solar System comets

L. Matrà, M. A. MacGregor, P. Kalas +13

Recent ALMA observations present mounting evidence for the presence of exocometary gas released within Kuiper belt analogues around nearby main sequence stars. This represents a un…

Millimeter Emission Structure in the first ALMA Image of the AU Mic Debris Disk

Meredith A. MacGregor, David J. Wilner, Katherine A. Rosenfeld +9

We present 1.3 millimeter ALMA Cycle 0 observations of the edge-on debris disk around the nearby, ~10 Myr-old, M-type star AU Mic. These observations obtain 0.6 arcsec (6 AU) resol…
