Title: Imager-Corrected NIR Spectro-Photometry of a Hot Jupiter

Abstract: Spectro-photometry of exoplanets and their host stars provides valuable insight into exoplanetary atmospheres. When a planet transits in front of its host star, spectro-photometric measurements give the planet's atmospheric conditions at its terminator. Gases with significant spectral features can be detected and then modeled to reveal how abundant they are in the planet. The near-infrared spectral windows, in particular, include features from molecules like carbon monoxide, carbon dioxide and methane. We propose to use the Triplespec single slit spectrograph at Palomar to search for these molecules in either Tres-2b or WASP-10b. Our method will include the heretofore- unexplored technique of ``imager correction''. By using the spectrograph's guider camera to correct for slit loss and spectral slope shifts, we will obtain the planet's radius as a function of wavelength. Our measurements of Tres-2b or WASP-10b will provide knowledge of a whole new Hot Jupiter planetary atmosphere, growing the small list of spectroscopically constrained planets.
