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…
A PIONIER View on Mass-Transferring Red Giants
Henri M. J. Boffin, Nicolas Blind, Michel Hillen +3
Symbiotic stars display absorption lines of a cool red giant together with emission lines of a nebula ionized by a hotter star, indicative of an active binary star system in which…
