摘要: Abstract DAVINCI is a dilute aperture nulling coronagraph that has the potential of directly detecting an Earth in habitable zone around ~100 nearby stars. The novel feature this mission concept to replace filled 5-6 meter telescope with 4 by1.1 telescopes phased array, dramatically reducing cost by potentially factor 5-10. 1 Introduction one 7 Exoplanet proposals were selected for one-year study NASA. direct detection Earthlike planets stars very challenging problem received great deal attention last few years. visible interferometer detect significant number such targets (around ~ 100 stars, see Figure 2) at order magnitude lower than competing techniques. space and on ground strong function diameter telescope.
