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…
Young Brown Dwarfs as Giant Exoplanet Analogs
Jacqueline K. Faherty, Kelle L. Cruz, Emily L. Rice +1
Young brown dwarfs and directly-imaged exoplanets have enticingly similar photometric and spectroscopic characteristics, indicating that their cool, low gravity atmospheres should…
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…
