Scientific paper

With our minds focussed on the direct detection of planets using the space interferometry mission DARWIN/TPF, we have made an attempt to identify how the set of ESO Very Large Telescope Interferometer instruments available now, and in the near future (VINCI, MIDI, AMBER, GENIE, FINITO and PRIMA) could contribute to the DARWIN/TPF precursory science program. In particular related to the identification of a short list of science stars to be observed with DARWIN/TPF. We have identified two research projects which can be viewed as DARWIN/TPF precursory science and can be embarked upon shortly using the available VLTI instruments: (1) the direct measurement of stellar angular diameters of a statistically meaningful sample of main-sequence stars with AMBER; (2) an interferometric study of those main-sequence stars that exhibit an infrared excess with either AMBER or MIDI. On the longer run, VLTI can obviously make a significant impact through the exploitation of the infrared nuller GENIE and the astrometric facility PRIMA.
