Mapping Alien Continents: Achieving Optical VLBI for Exoplanet Imaging

PaulStankusBrookhaven Science Associates The scientific goal of the proposed work will be reconstructing the image, ie resolving surface features, of an Earth-like exoplanet around a nearby star as seen in visible light. The innovation is in two stages. First, the design of a new kind of nulling interferometer - dynamic hierarchical nulling - combining inputs []
