Software preparation for data reduction of interferometric observations, feasibility studies and simulations of interferometric observations
Interferometric observations of close binaries, multiple systems and sub-stellar companions.
Development of hardware and/or relevant technology for interferometric instruments, e.g. for the ESO VLTI, based on integrated optics with active noise control, e.g. for fringe tracker (concept, design, test)
Complementary observations of sub-stellar companions with astrometry, transit technique, and direct imaging.
Photometric monitoring, observations of young stars to find eclipsing stellar and sub-stellar binaries.
Preparatory work on mass determination of sub-stellar companions with theoretical atmosphere models and empirical evolutionary tracks.
