Characterizing Giant Exoplanets through Multiwavelength Transit Observations: HD 189733b

Observing the transits of exoplanets in multiple wavelengths enables the characterization of their atmospheres. We used the Wyoming Infrared Observatory to obtain high precision photometry on HD 189733b, one of the most studied exoplanets. We employed the photometry package AIJ and Bayesian statistics in our analysis. Preliminary results suggest a wavelength dependence in the size of the exoplanet, indicative of scattering in the atmosphere.
