29 October 2009Speaker: Ruth Murray-Clay (CfA) Title:Frontier Planets: Wide Separation Giants and Hot Super-Earths Abstract:Though ~400 planets are currently known, discoveries at the observational frontiers continue to yield new classes of planets. Several giants have now been directly imaged, offering the first view of extrasolar planets at wide separations from their host stars. At the opposite extremes in mass and separation, super-Earths have been detected as they transit their stars. I will describe how wide separation giants inform our theoretical understanding of the formation and evolution of planetary systems and how upcoming observations of super-Earths can constrain the atmospheric evolution of hot planets.
