Effects of Mirror Seeing on High-Contrast Adaptive Optics Instruments

Melisa Tallis, Vanessa P. Bailey, Bruce Macintosh +6

Ground-based direct imaging surveys like the Gemini Planet Imager Exoplanet Survey (GPIES) rely on Adaptive Optics (AO) systems to image and characterize exoplanets that are up to…

Air, Telescope, and Instrument Temperature Effects on the Gemini Planet Imager's Image Quality

Melisa Tallis, Vanessa P. Bailey, Bruce Macintosh +5

The Gemini Planet Imager (GPI) is a near-infrared instrument that uses Adaptive Optics (AO), a coronagraph, and advanced data processing techniques to achieve very high contrast im…

Status and performance of the Gemini Planet Imager adaptive optics system

Vanessa P. Bailey, Lisa A. Poyneer, Bruce A. Macintosh +14

The Gemini Planet Imager is a high-contrast near-infrared instrument specifically designed to image exoplanets and circumstellar disks over a narrow field of view. We use science d…

Planets Around Low-Mass Stars (PALMS). V. Age-Dating Low-Mass Companions to Members and Interlopers of Young Moving Groups

Brendan P. Bowler, Evgenya L. Shkolnik, Michael C. Liu +22

We present optical and near-infrared adaptive optics (AO) imaging and spectroscopy of 13 ultracool (>M6) companions to late-type stars (K7-M4.5), most of which have recently been i…

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…

Improving Signal to Noise in the Direct Imaging of Exoplanets and Circumstellar Disks

Zahed Wahhaj, Lucas A. Cieza, Dimitri Mawet +10

We present a new algorithm designed to improve the signal to noise ratio (SNR) of point and extended source detections in direct imaging data. The novel part of our method is that…
