A Spitzer Transmission Spectrum for the Exoplanet Gj 436b, Evidence for Stellar Variability, and Constraints on Dayside Flux Variations

In this paper, we describe a uniform analysis of eight transits and eleven secondary eclipses of the extrasolar planet GJ 436b obtained in the 3.6, 4.5, and 8.0 μm bands using the IRAC instrument on the Spitzer Space Telescope between UT 2007 June 29 and UT 2009 February 4. We find that the best-fit...
