Title: Search for water vapor in a super-Earth exoplanet

Abstract: We propose observations that will identify the nature and thermal structure in the atmosphere of the recently discovered exoplanet GJ 1214b, whose low mass puts the planet in the category of super-Earths, and whose relatively small size is consistent with it being water-rich. Thus, this is our first opportunity to quantify the complex atmosphere of a super-Earth. Observations with Keck can help determine the most important question about these planets, such as: 1) Are super-Earths more closely aligned to large terrestrial planets or small gas giant planets? and 2) Has a super-Earth with significant water abundance been discovered?
