Abstract

Multiple different groups have generated a wide variety of mission concepts for direct exoplanet imaging, incorporating a variety of spacecraft architectures and starlight suppression systems. Here, we present a framework for modeling exoplanet surveys based on these concepts, including systematic methods for predicting their expected science yields, thereby allowing for the direct comparison of different mission concepts. We describe in detail the components of this modeling framework and demonstrate how we can generate simulated planetary populations that are broadly consistent with the results of the Kepler transit survey and previous radial velocity surveys. We present results of end-to-end mission simulations, focusing in particular on the 2.4 m aperture scale provided by the Astrophysics Focused Telescope Asset and set top level requirements for the coronagraph needed to discover and characterize new planets with this telescope.
