Post-processing the VLTI fringe-tracking data: First measurements of stars
Jean-Baptiste Le Bouquin, Roberto Abuter, Pierre Haguenauer +3
At the Very Large Telescope Interferometer, the purpose of the fringe-tracker FINITO is to stabilize the optical path differences between the beams, allowing longer integration tim…
First result with AMBER+FINITO on the VLTI: The high-precision angular diameter of V3879 Sgr
Jean-Baptiste Le Bouquin, Bertrand Bauvir, Pierre Haguenauer +3
Our goal is to demonstrate the potential of the interferometric AMBER instrument linked with the Very Large Telescope Interferometer (VLTI) fringe-tracking facility FINITO to deriv…
Extreme adaptive optics imaging with a clear and well-corrected off-axis telescope sub-aperture
E. Serabyn, K. Wallace, M. Troy +4
Rather than using an adaptive optics (AO) system to correct a telescope s entire pupil, it can instead be used to more finely correct a smaller sub-aperture. Indeed, existing AO sy…
Bright Localized Near-Infrared Emission at 1-4 AU in the AB Aurigae Disk Revealed by IOTA Closure Phases
R. Millan-Gabet, J. D. Monnier, J. -P. Berger +13
We report on the detection of localized off-center emission at 1-4 AU in the circumstellar environment of the young stellar object AB Aurigae. We used closure phase measurements in…
Few Skewed Disks Found in First Closure-Phase Survey of Herbig Ae/Be stars
J. D. Monnier, J. -P. Berger, R. Millan-Gabet +13
Using the 3-telescope IOTA interferometer on Mt. Hopkins, we report results from the first near-infrared (lambda=1.65 mu) closure-phase survey of Young Stellar Objects (YSOs). Thes…
Planar Integrated Optics and astronomical interferometry
Pierre Kern, Jean-Philippe Berger, Pierre Haguenauer +2
Integrated optics (IO) is an optical technology that allows to reproduce optical circuits on a planar substrate. Since 1996, we have investigated the potentiality of IO in the fram…
