4:00 pm: Summer Colloquium Series. "NASA Goes Green: How We Recycled the Deep Impact Spacecraft," Dr. Jessie Christiansen, CfA. Preceded by refreshments at 3:30 pm. Phillips Auditorium.

Abstract:The EPOCh (Extrasolar Planet Observation and Characterisation) project forms part of the EPOXI mission of opportunity utilising the Deep Impact flyby spacecraft. The aim of the project was to observe known transiting extrasolar planets, each target for several weeks at a time, to construct high cadence, high precision light curves. We analyse these data for evidence of additional planets in several ways - by searching for additional transits, and by searching for transit timing variations. We also use the data to refine our knowledge of the known transiting planet, including attempting to learn more about the atmospheric properties by looking for signals of reflected light at secondary eclipse.
