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.
