Abstract
VLTi Spectro-Imager (VSI) is a proposition for a second generation VLTI
instrument which is aimed at providing the ESO community with the
capability of performing image synthesis at milli-arcsecond angular
resolution. VSI provides the VLTI with an instrument able to combine 4
telescopes in a baseline version and optionally up to 6 telescopes in
the near-infrared spectral domain with moderate to high spectral
resolution. The instrument contains its own fringe tracker in order to
relax the constraints onto the VLTI infrastructure. VSI will do imaging
at the milli-arcsecond scale with spectral resolution of: a) the close
environments of young stars probing the initial conditions for planet
formation; b) the surfaces of stars; c) the environment of evolved
stars, stellar remnants and stellar winds, and d) the central region of
active galactic nuclei and supermassive black holes. The science cases
allowed us to specify the astrophysical requirements of the instrument
and to define the necessary studies of the science group for phase A.
