InnoPOL: an EMCCD imaging polarimeter and 85-element curvature AO system on the 3.6-m AEOS telescope for cost effective polarimetric speckle suppression
David Harrington, Svetlana Berdyugina, Mark Chun +3
The Hokupa'a-85 curvature adaptive optics system components have been adapted to create a new AO-corrected coudé instrument at the 3.67m Advanced Electro-Optical System (AEOS) tele…
The Gemini NICI Planet-Finding Campaign: Asymmetries in the HD 141569 disc
Beth A. Biller, Michael C. Liu, Ken Rice +8
We report here the highest resolution near-IR imaging to date of the HD 141569A disc taken as part of the NICI Science Campaign. We recover 4 main features in the NICI images of th…
Astrometric Calibration of the Gemini NICI Planet-Finding Campaign
Thomas L. Hayward, Beth A. Biller, Michael C. Liu +6
We describe the astrometric calibration of the Gemini NICI Planet-Finding Campaign. The Campaign requires a relative astrometric accuracy of 20 mas across multi-year time…
The Gemini NICI Planet-Finding Campaign: The Offset Ring of HR 4796 A
Zahed Wahhaj, Michael C. Liu, Beth A. Biller +7
We present J, H, CH_4 short (1.578 micron), CH_4 long (1.652 micron) and K_s-band images of the dust ring around the 10 Myr old star HR 4796 A obtained using the Near Infrared Coro…
Magellan Adaptive Optics first-light observations of the exoplanet Pic b. I. Direct imaging in the far-red optical with MagAO+VisAO and in the near-IR with NICI
Jared R. Males, Laird M. Close, Katie M. Morzinski +20
We present the first ground-based CCD (m) image of an extrasolar planet. Using MagAO's VisAO camera we detected the extrasolar giant planet (EGP) Pictoris b in -short…
The Gemini NICI Planet-Finding Campaign: The Orbit of the Young Exoplanet beta Pictoris b
Eric L. Nielsen, Michael C. Liu, Zahed Wahhaj +12
We present new astrometry for the young (12--21 Myr) exoplanet beta Pictoris b taken with the Gemini/NICI and Magellan/MagAO instruments between 2009 and 2012. The high dynamic ran…
