Observing Strategies for the NICI Campaign to Directly Image Extrasolar Planets
Beth Biller, Etienne Artigau, Zahed Wahhaj +7
We discuss observing strategy for the Near Infrared Coronagraphic Imager (NICI) on the 8-m Gemini South telescope. NICI combines a number of techniques to attenuate starlight and s…
Performance of the Near-infrared coronagraphic imager on Gemini-South
Mark Chun, Doug Toomey, Zahed Wahhaj +8
We present the coronagraphic and adaptive optics performance of the Gemini-South Near-Infrared Coronagraphic Imager (NICI). NICI includes a dual-channel imager for simultaneous spe…
NICI: combining coronagraphy, ADI, and SDI
Etienne Artigau, Beth A. Biller, Zahed Wahhaj +9
The Near-Infrared Coronagraphic Imager (NICI) is a high-contrast AO imager at the Gemini South telescope. The camera includes a coronagraphic mask and dual channel imaging for Spec…
Cool Customers in the Stellar Graveyard III: Limits to Substellar Objects around nearby White Dwarfs using CFHT
J. H. Debes, J. Ge, C. Ftaclas
Results from a groundbased high contrast imaging survey of thirteen nearby white dwarfs for substellar objects is presented. We place strict upper limits on the type of substellar…
High Dynamic Range and the Search for Planets
A. T. Tokunaga, C. Ftaclas, J. R. Kuhn +1
General arguments for optimized coronagraphy in the search for planets are presented. First, off-axis telescopes provide the best telescopic platforms for use with coronagraphy, an…
Near-infrared coronagraphic imaging of the circumstellar disk around TW Hydrae
David E. Trilling, David W. Koerner, Jason W. Barnes +2
We present ground-based near-infrared (H-band) imaging of the circumstellar disk around the nearby classical T Tauri star TW Hydrae. The scattered light image shows a face-on disk…
