Constraining Exoplanet Mass from Transmission Spectroscopy [PDF]

Science, 2013
Weighing Up Exoplanets The mass of a planet is important to know, but it is difficult to determine for an exoplanet. If a transmission spectrum of an exoplanet is available, de Wit and Seager (p. 1473 ) show that it is possible to determine its mass based on the properties of its ...
