Title: A New Method to Measure the H-Ks Color of the Daysides of Hot Jupiters

Abstract: We propose to observe the secondary eclipse of the hot Jupiter WASP- 103b to validate a technique we are referring to as ``chromometry.'' We have already had initial success with chromometry in the optical observing exoplanet transits, and believe that this new technique will allow us to measure the H-Ks colors of the eclipse, and hence the planetary dayside, with a precision two to three times greater than what is achievable using traditional photometry methods. The validation of this technique would allow us to measure the H-Ks colors of three to four times as many hot Jupiters as currently have H- and Ks-band eclipse measurements, and would allow us to measure the eclipse color of planets around extremely bright host stars. This second point is particularly exciting in the context of the upcoming TESS mission, since secondary eclipses of the bright hot Jupiters that TESS is expected to discover are difficult, if not impossible, to measure from the ground using traditional methods. Chromometry would therefore allow us to substantially increase TESS's science yield.
