| « Detection and Characterization of Exoplanetary Atmospheres » |

For nearly one decade, transit events have provided an extraordinary abundance of information for close in Jupiter size exoplanets. Most notably, transits permit a precise measurement of a planets mass, radius, and temperature which has led to knowledge of planetary bulk composition as well as atmospheric content and structure. Enough transiting hot-Jupiters and their characteristics are now known such that two different classes of these planets are now emerging, the beginnings of comparative exoplanetology.
In this talk I will discuss previous and ongoing space and ground based transit observations as well as the interpretations of such results, focusing primarily on planetary atmospheres. Finally, I will discuss the future prospects for transit science considering planned future space and ground based telescopes. |
