Paper Abstract

The WFIRST mission was originally ended as a wide-field survey facility. With the change to a 2.4-m telescope, the mission is capable of carrying an effective coronagraph for exoplanet imaging. The baseline architecture allows use of a hybrid lyot or shaped pupil coronagraph, feeding a imager and integral field spectrograph. This will allow imaging and photometry of mature nearby planets and zodiacal disks in reflected light, as well as spectroscopy of the brightest targets. I will discuss the scientific motivations of the mission and show simulated science capabilities, and discuss the process towards definition of a science mission.
