Extrasolar Planets: September 2008

WHEN: November 19, 2008 (Wed) ~ November 21, 2008 (Fri)
WHERE: Salle Cassini, Observatoire Paris, Paris, France

Exoplanets are being discovered at an ever accelerating pace, and planetary scientists and astronomers are increasingly called upon to make the transition from discovery to characterization. This workshop aims at bringing together different scientific communities: solar system planetary scientists, brown dwarf and exoplanet modellers and observers, molecular spectroscopy and instrument development experts.

We will cover different topics: radiative transfer, line lists, photochemical models, dynamics, and observations using space- and ground-based facilities. Current results will be discussed in the context of the preparation of upcoming missions, SPITZER, JWST, and SPICA, and the next generation of direct detection mission concepts from ground andspace.

NICMOS Confirmation of an Extrasolar Panet Candidate Directly Detected with ACS

With ACS/HRC coronagraphy, we have achieved the direct detection of a planet candidate in F606W and F814W around a bright nearby star with a debris belt. The planet candidate lies 18 astronomical units interior to the dust belt and we detect counterclockwise orbital motion in observations separated by 1.75 years. The candidate has mass no greater than three Jupiter masses based on an analysis of its luminosity and the dynamical argument that a significantly more massive object would disrupt the dust belt.

The NASA Exoplanet Science Institute announces the introduction of the Sagan Postdoctoral Fellowship Program and solicits applications for fellowships to begin in the fall of 2009.

The Sagan Fellowships support outstanding recent postdoctoral scientists to conduct independent research that is broadly related to the science goals of the NASA Exoplanet Exploration area. The primary goal of missions within this program is to discover and characterize planetary systems and Earth-like planets around nearby stars.

This amendment announces a new proposal opportunity in Appendix D.10 entitled "MOST U.S. Guest Observer Program - Cycle 1." This program element solicits proposals for the acquisition and analysis of new scientific data from the MOST (Microvariability and Oscillations of STars) observatory through a partnership between NASA and the Canadian Space Agency (CSA). Observations associated with the MOST U.S. Guest Observer -- Cycle 1 solicitation will begin on or around February 1, 2009 and awards will have a 12-month duration.
