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…
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…
Discovery and Characterization of a Faint Stellar Companion to the A3V Star Zeta Virginis
Sasha Hinkley, Ben R. Oppenheimer, Douglas Brenner +17
Through the combination of high-order Adaptive Optics and coronagraphy, we report the discovery of a faint stellar companion to the A3V star zeta Virginis. This companion is ~7 mag…
