Abstract

We report recent success to stabilize the VLTI/MIDI-10um beam-combiner with K-band fringe tracking, provided by PRIMA (FSU). After encouraging commissioning results, presented during the last SPIE, we accomplished in November 2011 a successful run of science demonstration. A broad range of targets were observed, from planet-hosting stars over YSO disks to AGN. We will present first results, focussing on the improvements on sensitivity and precision with respect to classical MIDI stand-alone observations. MIDI broad-band dispersion and group-delay can be reliably predicted by the fringe tracker to enable coherent integration beyond coherence time at the lambda/10 precision level.
