Abstract

Time has come for the VLTI to prepare its jump into the visible domain, revealing many physical processes occuring in stars, planets and galaxies. Visible interferometry has a superior angular resolution than its IR siblings with the same baselines. Science with a visible VLTI ranges from evolved stars mass loss, fundamental parameters of main sequence stars, surface-brightness relation refinement, and the progenitors of gravitational waves ... These critical science cases are becoming feasible thanks to recent instrumental improvements: better detectors, adaptive optics, fringe trackers, use of optical fibers and integrated optics. The appeal for visible light at VLTI is now stronger than ever because IR has already been explored substantially at ESO. This presentation further addresses possible path forward toward a visible instrument with scientific-driven specifications. We will discuss the benefits of a survey-type observing program to allow it to operate at its full potential.
