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…
Fundamental limitations of high contrast imaging set by small sample statistics
Dimitri Mawet, Julien Milli, Zahed Wahhaj +9
In this paper, we review the impact of small sample statistics on detection thresholds and corresponding confidence levels (CLs) in high contrast imaging at small angles. When look…
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…
