Status of Space-based Segmented-Aperture Coronagraphs for Characterizing Exo-Earths Around Sun-Like Stars
We aim to inform Astro2020 of the status of coronagraph technology for use with a space-based segmented and/or partially obscured primary mirror. Our design and modeling study has determined that multiple coronagraph architectures can achieve the necessary performance. Some preliminary observatory requirements appear challenging but achievable.
