Speckle Suppression with the Project 1640 Integral Field Spectrograph
Justin R. Crepp, Laurent Pueyo, Douglas Brenner +15
Project 1640 is a high-contrast imaging instrument recently commissioned at Palomar observatory. A combination of a coronagraph with an integral field spectrograph (IFS), Project 1…
A New High Contrast Imaging Program at Palomar Observatory
Sasha Hinkley, Ben R. Oppenheimer, Neil Zimmerman +19
We describe a new instrument that forms the core of a long-term high contrast imaging program at the 200-inch Hale Telescope at Palomar Observatory. The primary scientific thrust i…
Establishing Alpha Oph as a Prototype Rotator: Improved Astrometric Orbit
Sasha Hinkley, John D. Monnier, Ben R. Oppenheimer +24
The nearby star Alpha Oph (Ras Alhague) is a rapidly rotating A5IV star spinning at ~89% of its breakup velocity. This system has been imaged extensively by interferometric techniq…
Science drivers and requirements for an Advanced Technology Large Aperture Space Telescope (ATLAST): Implications for technology development and synergies with other future facilities
Marc Postman, Tom Brown, Kenneth Sembach +11
The Advanced Technology Large-Aperture Space Telescope (ATLAST) is a concept for an 8-meter to 16-meter UVOIR space observatory for launch in the 2025-2030 era. ATLAST will allow a…
The Lyot Project Direct Imaging Survey of Substellar Companions: Statistical Analysis and Information from Nondetections
Jérémy leconte, Rémi Soummer, Sasha Hinkley +14
The Lyot project used an optimized Lyot coronagraph with Extreme Adaptive Optics at the 3.63m Advanced Electro-Optical System telescope (AEOS) to observe 86 stars from 2004 to 2007…
New Completeness Methods for Estimating Exoplanet Discoveries by Direct Detection
Robert A. Brown, Remi Soummer
We report new methods for evaluating realistic observing programs that search stars for planets by direct imaging, where observations are selected from an optimized star list, and…
