Title: Exoplanetology with near-simultaneous optical and infrared transits

Abstract: We propose to use the NESSI and WHIRC instruments on the WIYN telescope to observe transits of giant exoplanets near-simultaneously at optical and infrared wavelengths. This is a pilot study to test the suitability of this method to constrain wavelength-dependent exoplanet radii. In planets with hazes and high altitude clouds there should be strong Rayleigh scattering. This results in larger apparent exoplanet radii at shorter optical wavelengths. However, at infrared wavelengths, the planets start to appear larger again owing to molecular bands. We are aiming to test whether the near-simultaneous use of NESSI and WHIRC is suitable to explore this type of science. If successful, we intend to propose a large program of exoplanet atmosphere characterization in future semesters. Such a program would complement studies of exoplanet atmospheres at longer wavelengths with facilities like JWST. We intend to waive the proprietary period for these data to maximize their usefulness to the community.
