Yet, these multiple systems are usually overlooked or discarded in most direct imaging surveys, as they prove difficult to image at high-contrast using coronographs. This is particularly the case for compact binaries (less than 1\" angular separation) with similar stellar magnitudes, where no existing coronagraph can provide high-contrast regime.
