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…
A Close Companion Search around L Dwarfs using Aperture Masking Interferometry and Palomar Laser Guide Star Adaptive Optics
David Bernat, Antonin H. Bouchez, Michael Ireland +22
We present a close companion search around sixteen known early-L dwarfs using aperture masking interferometry with Palomar laser guide star adaptive optics. The use of aperture mas…
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…
