Getting to the Core of Exoplanets: From Gas to Ice Giants
November 13, 2007 / Posted by: Shige Abe
The measured masses and orbits of the 200 secure exoplanets within 200 pc reveal the processes of formation and subsequent dynamics. Several planets reveal information on their cores and interiors. Multiple-planet systems, especially those in resonances, inform us about migration, scattering, and capture. Planets from 5-14 Earth masses are now detectable, and several have been found. The Kepler Mission and a new 2.4-m “Automated Planet Finder” telescope at Lick Observatory portend the detection of rocky planets.
