First Light for the GRAVITY+ Adaptive Optics: Extreme Adaptive Optics for the Very Large Telescope Interferometer
GRAVITY+ Collaboration, :, F. Allouche +137
GRAVITY+ improves by orders of magnitude the sensitivity, sky-coverage and contrast of the Very Large Telescope Interferometer (VLTI). A central part of this project is the develop…
First Light for GRAVITY Wide: Large Separation Fringe Tracking for the Very Large Telescope Interferometer
GRAVITY+ Collaboration, :, R. Abuter +114
GRAVITY+ is the upgrade of GRAVITY and the Very Large Telescope Interferometer (VLTI) with wide-separation fringe tracking, new adaptive optics, and laser guide stars on all four 8…
Improving the astrometric performance of VLTI-PRIMA
J. Woillez, R. Abuter, L. Andolfato +18
In the summer of 2011, the first on-sky astrometric commissioning of PRIMA-Astrometry delivered a performance of 3 m'' for a 10 '' separation on bright objects, orders of magnitude…
The ESPRI project: astrometric exoplanet search with PRIMA I. Instrument description and performance of first light observations
J. Sahlmann, T. Henning, D. Queloz +42
The ESPRI project relies on the astrometric capabilities offered by the PRIMA facility of the Very Large Telescope Interferometer for the discovery and study of planetary systems.…
Narrow-angle astrometry with PRIMA
J. Sahlmann, D. Ségransan, A. Mérand +16
The Extrasolar Planet Search with PRIMA project (ESPRI) aims at characterising and detecting extrasolar planets by measuring the host star's reflex motion using the narrow-angle as…
First results from fringe tracking with the PRIMA fringe sensor unit
J. Sahlmann, R. Abuter, S. Menardi +12
The fringe sensor unit (FSU) is the central element of the phase referenced imaging and micro-arcsecond astrometry (PRIMA) dual-feed facility for the Very Large Telescope interfero…
