GJ1214_trans_spec_simple

The optical and near-infrared transmission spectrum of GJ 1214b. The planet-to-star radius ratio derived from the transit depth is shown as a function of wavelength. The right vertical axis gives the corresponding size of the exoplanet in Earth radii. Our measurements with Magellan/IMACS (black points) are shown along with near-infrared data from the Hubble (green) and Spitzer (red) Space Telescopes. The solid lines are the best-fitting models for cloudy and hazy atmospheres. Adapted from Rackham et al. 2017.
