NExSS is a cross-divisional initiative from NASA to create a research coordination network (RCN) with an emphasis on studying extrasolar planets and the potential for habitability. An RCN is a virtual structure to support groups of investigators to communication and coordinate research and educational activity. At Berkeley our contributions are the observations of extrasolar planets via direct imaging, the transit technique, and Doppler spectroscopy, plus the theoretical study of planet formation and subsequent evolution.
The Gemini Planet Imager (GPI) is a new science instrument that exploits the latest generation of adaptive optics technology, coronagraphy and detectors. We have successfully commissioned GPI at the Gemini South telescope in Chile and in 2014 we started a three year science program called GPIES (GPI Exoplanet Survey) that will survey 600 stars for the presence of young giant planets.
