Title: Eclipse and Transmission Spectra of WASP-12b
Abstract: The hot Jupiter WASP-12b has been observed in both transit and eclipse from the ground and using the Hubble Space Telescope. In both cases, the observations do not appear to converge on a consistent view of the planetary atmosphere. Two sets of HST near-infrared transit transmission observations showed, first, a lack of water in the atmosphere, and second, a strong water feature. In eclipse, the planetary emission spectrum appears roughly isothermal, expect for potentially strong emission in the K-band. In both cases, transit and eclipse, K-band spectra are needed to resolve the atmospheric uncertainties. We propose to use LUCI/MOS in binocular mode to simultaineously observe transit transmission and eclipse spectra of WASP-12b in both H and K. Based on our previous observations using the same observing, we anticipate that these observations will have comparable resolution and flux precision as the Hubble measurements, and will be able to clearly differentiate between possible atmospheric models.
