  4. IAU Colloquium 200 S. Ridgway - AAAC - 10/12/06

  5. Active ExoPlanet/Exosystem Observational Programs • Radial velocity monitoring • Transit searches • Microlensing • YSO’s, preplanetary and debris disks S. Ridgway - AAAC - 10/12/06

  6. Recent Results for ExoSystems • Many detections • Rich variety of exosystems • Multi-planet systems • Lower masses • Closer to solar system analogues • Potentially Earth-like planets may be common S. Ridgway - AAAC - 10/12/06

  7. Status of Major NASA ExoPlanet Missions • Kepler - exoplanet study by transits • Statistics of short-period planets - down to Earth-size • In implementation • SIM - exoplanet study by astrometry + astrophysics • Detection of nearby candidate Earth-like planets • In formulation • Advanced stage of engineering readiness • Currently delayed - engineering/prototyping/science preparation continues • TPF - exoplanet study by spectroscopy; astrophysics • Direct study of candidate Earth-like planets • In pre-formulation • Key (enabling) technical demonstrations completed in infrared interferometry and visible coronagraphy • Currently deferred - technical/scientific development continues Navigator S. Ridgway - AAAC - 10/12/06

  8. Astronomy and Astrophysics Decade Review2007 - 2010 AAAC ExoPlanet Task Force2006 - 2007 S. Ridgway - AAAC - 10/12/06

  9. The ExoPTF Charge (draft) • This letter is to request that the AAAC establish an Exo-Planet Task Force as a subcommittee to jointly advise NSF and NASA on the future of the search for and study of exo-planets, planetary systems, Earth-like planets and habitable environments around other stars. S. Ridgway - AAAC - 10/12/06

  10. The ExoPTF Charge (draft) • The ExoPTF is asked to recommend a 15-year strategy to detect and characterize exo-planets and planetary systems, and their formation and evolution, including specifically the identification of nearby candidate Earth-like planets and study of their habitability. The strategy may include planning and preparation for facilities and missions beyond the 15-year horizon. S. Ridgway - AAAC - 10/12/06

  11. The ExoPTF Charge (draft) 1. The key scientific questions and issues, in the context of recent developments in exo-planet science and planet formation; 2. Measurement techniques, their enabling technologies, and their implications for future survey and measurement directions and priorities; 3. Specific types of experiments (e.g., radial velocity measurements, transit searches, microlensing, adaptive optics, coronagraphy) with respect to their expected scientific return and contributions; 4. The potential and complementary science return from measurements at different wavelengths; 5. Major decision points in the exo-planet study process; 6. Important steps, precursor instrumentation on the ground or in space, R&D, and other work required in preparation for, in support of, or alternative to, these and related experiments and missions; 7. Identification of the nature and scope of investments in key technologies relevant to the scientific goals of the program; 8. The complementary ground-based and space-based research opportunities, coordination between funding agencies and possible synergistic advances; 9. Opportunities for cooperation, coordination or synergy with international programs, such as the Darwin mission at the European Space Agency, or the Ground-based European Nulling Interferometer Experiment (GENIE) and Very Large Telescope Interferometer (VLTI) projects at the European Southern Observatory; 10. Cost effectiveness and affordability. S. Ridgway - AAAC - 10/12/06
