We present 2.12-2.23 ?m high contrast integral field spectroscopy of the extrasolar planet HR?8799 b. Our observations were obtained with OSIRIS on the Keck II telescope and sample the 2.2 ?m CH4 feature, which is useful for spectral classification and as a temperature diagnostic for ultracool objects. The spectrum of HR?8799 b is relatively featureless, with little or no methane absorption, and does not exhibit the strong CH4 seen in T dwarfs of similar absolute magnitudes. The spectrum is… 
RECONNAISSANCE OF THE HR 8799 EXOSOLAR SYSTEM. I. NEAR-INFRARED SPECTROSCOPY
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 Palomar 5 m Hale
Detection and Bulk Properties of the HR 8799 Planets with High-resolution Spectroscopy
Using the Keck Planet Imager and Characterizer, we obtained high-resolution (R ∼ 35,000) K-band spectra of the four planets orbiting HR 8799. We clearly detected H2O and CO in the atmospheres of HR
