MN Institute for Astrophysics Colloquium

Speaker: Vanessa Bailey, NASA Jet Propulsion Laboratory (JPL)
The WFIRST Coronagraph Instrument

The Coronagraph Instrument (CGI) for NASA's Wide Field Infrared Survey Telescope (WFIRST) will constitute a dramatic step forward for high-contrast imaging, integral field spectroscopy, and polarimetry of exoplanets and circumstellar disks, aiming to improve upon the sensitivity of current direct imaging facilities by 2-3 orders of magnitude. Furthermore, CGI will serve as a pathfinder for future exo-Earth imaging and characterization missions by demonstrating wavefront control, coronagraphy, and spectral retrieval in a new contrast regime. I will discuss the status of the instrument design, some of its key new technologies, and its potential science yield.
