GENIE: a ground-based precursor for the IRSI-Darwin mission
IAGL, University of Liège, B5C, 17 allée du 6 Août, 4000 Sart-Tilman, Belgium
A definition study for a Ground-based European Nulling Interferometry Experiment (GENIE) has been initiated by the European Space Agency (ESA) and the European Southern Observatory (ESO). This instrument is planned to be installed in 2006 on the VLTI at Mount Paranal, Chile. The primary objective of the GENIE experiment is to gain experience in the design, manufacture and operation of a nulling interferometer using a Darwin representative technology. Besides its technological goal, GENIE is designed to survey exozodiacal dust clouds around nearby stars and to study the brightest of them by means of low-resolution spectroscopy. GENIE also aims at low-mass companion detection, including hot Jupiters. In this paper, the expected performances of the GENIE interferometer are investigated as a function of the observation wavelength and of the performances of critical subsystems.
