The GRAVITY metrology system: narrow-angle astrometry via phase-shifting interferometry
M. Lippa, N. Blind, S. Gillessen +26
The VLTI instrument GRAVITY will provide very powerful astrometry by combining the light from four telescopes for two objects simultaneously. It will measure the angular separation…
The fiber coupler and beam stabilization system of the GRAVITY interferometer
O. Pfuhl, M. Haug, F. Eisenhauer +20
We present the installed and fully operational beam stabilization and fiber injection subsystem feeding the 2nd generation VLTI instrument GRAVITY. The interferometer GRAVITY requi…
A near-infrared interferometric survey of debris-disc stars. IV. An unbiased sample of 92 southern stars observed in H-band with VLTI/PIONIER
Steve Ertel, Olivier Absil, Denis Defrere +8
Context. Detecting and characterizing circumstellar dust is a way to study the architecture and evolution of planetary systems. Cold dust in debris disks only traces the outer regi…
Searching for faint companions with VLTI/PIONIER. II. 92 main sequence stars from the Exozodi survey
Lindsay Marion, Olivier Absil, Steve Ertel +6
The Exozodi survey aims to determine the occurrence rate of bright exozodiacal discs around nearby main sequence stars using infrared interferometry. Although the Exozodi survey ta…
Astrophotonic micro-spectrographs in the era of ELTs
N. Blind, E. Le Coarer, P. Kern +1
The next generation of Extremely Large Telescopes (ELT), with diameters up to 39 meters, will start opera- tion in the next decade and promises new challenges in the development of…
GRAVITY: the Calibration Unit
N. Blind, F. Eisenhauer, M. Haug +19
We present in this paper the design and characterisation of a new sub-system of the VLTI 2nd generation instrument GRAVITY: the Calibration Unit. The Calibration Unit provides all…
