Query: Scientific Return of Coronagraphic Exoplanet Imaging and Spectroscopy
  Using WFIRST   In this study, we explore and review the scientific potential for exoplanet
characterization by a high-contrast optical coronagraph on WFIRST/AFTA. We
suggest that the heterogeneity in albedo spectra and planet/star flux ratios as
a function of orbital distance, planet mass, and composition expected for the
giant exoplanets at separations from their primaries accessible to WFIRST will
provide unique constraints on giant planet atmospheres, evolution, aerosol and
cloud properties, and general theory. Such exoplanets are not merely
extrapolations of Jupiter and Saturn, but are likely to occupy a rich continuum
of varied behaviors. Each in themselves and jointly, optical spectra,
photometry, and polarization measurements of a diverse population of giant
exoplanets in the solar neighborhood has the potential to reveal a multitude of
fundamental features of their gas-giant chemistry, atmospheres, and formation.
Such a campaign will enrich our understanding of this class of planets beyond
what is possible with even a detailed exploration of the giants in our own
solar system, and will compliment ongoing studies of exoplanets in the infrared
and on close-in orbits inaccessible to coronagraphy.
