Electric Field Conjugation with the Project 1640 coronagraph
Eric Cady, Christoph Baranec, Charles Beichman +25
The Project 1640 instrument on the 200-inch Hale telescope at Palomar Observatory is a coronagraphic instrument with an integral field spectrograph at the back end, designed to fin…
The Kappa Andromedae System: New Constraints on the Companion Mass, System Age & Further Multiplicity
Sasha Hinkley, Laurent Pueyo, Jacqueline K. Faherty +29
Kappa Andromedae is a B9IVn star at 52 pc for which a faint substellar companion separated by 55 AU was recently announced. In this work, we present the first spectrum of the compa…
Precision near-infrared radial velocity instrumentation II: Non-Circular Core Fiber Scrambler
Peter P. Plavchan, Michael Bottom, Peter Gao +18
We have built and commissioned a prototype agitated non-circular core fiber scrambler for precision spectroscopic radial velocity measurements in the near-infrared H band. We have…
Reconnaissance of the HR 8799 Exosolar System I: Near IR Spectroscopy
B. R. Oppenheimer, C. Baranec, C. Beichman +29
We obtained spectra, in the wavelength range λ= 995 - 1769 nm, of all four known planets orbiting the star HR 8799. Using the suite of instrumentation known as Project 1640 on the…
