Multiband GPI Imaging of the HR 4796A Debris Disk
Christine H. Chen, Johan Mazoyer, Charles A. Poteet +36
We have obtained Gemini Planet Imager (GPI) J-, H-, K1-, and K2-Spec observations of the iconic debris ring around the young, main-sequence star HR 4796A. We applied several point-…
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…
Imaging the 44 AU Kuiper Belt-analogue debris ring around HD 141569A with GPI polarimetry
J. S. Bruzzone, S. Metchev, G. Duchene +53
We present the first polarimetric detection of the inner disk component around the pre-main sequence B9.5 star HD 141569A. Gemini Planet Imager H-band (1.65 micron) polarimetric di…
Detection of a low-mass stellar companion to the accelerating A2IV star HR 1645
Robert J. De Rosa, Eric L. Nielsen, Julien Rameau +50
The \, Myr A2IV star HR 1645 has one of the most significant low-amplitude accelerations of nearby early-type stars measured from a comparison of the {\it Hipparcos} and {…
Dynamical Mass Measurement of the Young Spectroscopic Binary V343 Normae AaAb Resolved With the Gemini Planet Imager
Eric L. Nielsen, Robert J. De Rosa, Jason Wang +44
We present new spatially resolved astrometry and photometry from the Gemini Planet Imager of the inner binary of the young multiple star system V343 Normae, which is a member of th…
First images of debris disks around TWA 7, TWA 25, HD 35650, and HD 377
Élodie Choquet, Marshall D. Perrin, Christine H. Chen +15
We present the first images of four debris disks observed in scattered light around the young (4--250 Myr old) M dwarfs TWA 7 and TWA 25, the K6 star HD 35650, and the G2 star HD 3…
The M-dwarfs in Multiples (MinMs) survey - I. Stellar multiplicity among low-mass stars within 15 pc
K. Ward-Duong, J. Patience, R. J. De Rosa +6
We present a large-scale, volume-limited companion survey of 245 late-K to mid-M (K7-M6) dwarfs within 15 pc. Infrared adaptive optics (AO) data were analysed from the Very Large T…
The Brown-dwarf Atmosphere Monitoring (BAM) Project II: Multi-epoch monitoring of extremely cool brown dwarfs
A. Rajan, J. Patience, P. A. Wilson +6
With the discovery of Y dwarfs by the WISE mission, the population of field brown dwarfs now extends to objects with temperatures comparable to those of Solar System planets. To in…
Five Debris Disks Newly Revealed in Scattered Light from the HST NICMOS Archive
Rémi Soummer, Marshall D. Perrin, Laurent Pueyo +12
We have spatially resolved five debris disks (HD 30447, HD 35841, HD 141943, HD 191089, and HD 202917) for the first time in near-infrared scattered light by reanalyzing archival H…
The Brown dwarf Atmosphere Monitoring (BAM) Project I: The largest near-IR monitoring survey of L- & T-dwarfs
P. A. Wilson, A. Rajan, J. Patience
Using SofI on the 3.5m New Technology Telescope, we have conducted an extensive near-infrared monitoring survey of an unbiased sample of 69 brown dwarfs spanning the L0 and T8 spec…
Sub-millimeter observations of IRAS and WISE debris disk candidates
J. Bulger, T. Hufford, A. Schneider +7
A set of six debris disk candidates identified with IRAS or WISE excesses were observed at either 350 um or 450 um with the CSO. Five of the targets - HIP 51658, HIP 68160, HIP 735…
