Seminar Detail
Getting to the Core of Exoplanets: From Gas to Ice Giants
Presenter: Geoff Marcy
December 3, 2007 11:00 AM Pacific
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.

Without a Polycom...There are two ways to participate:
1) You can listen to the seminar on the telephone while viewing the slides in WebEx (see WebEx instructions above). The NASA conference phone number will be displayed when joining the WebEx meeting.
2) You can watch the Realplayer webcast at: http://vanseg-1.arc.nasa.gov/2007/AB071203-01.ram and view the slides in WebEx (see WebEx instructions above) There is a 30 second delay for the webcast, so you will need to control the slides manually using the arrow buttons in WebEx. Questions for the speaker can be posted in the WebEx chat area to be answered at the end of the talk. Do not try to watch the Realplayer webcast at the same time as the Polycom or the phone.December 21, 2007
