Impact of water vapor seeing on mid-infrared high-contrast imaging at ELT scale
Olivier Absil, Christian Delacroix, Gilles Orban de Xivry +9
The high-speed variability of the local water vapor content in the Earth atmosphere is a significant contributor to ground-based wavefront quality throughout the infrared domain. U…
CHARA/SPICA: a 6-telescope visible instrument for the CHARA Array
Denis Mourard, Philippe Berio, Cyril Pannetier +25
With a possible angular resolution down to 0.1-0.2 millisecond of arc using the 330 m baselines and the access to the 600-900 nm spectral domain, the CHARA Array is ideally configu…
SPICA-FT: The new fringe tracker of the CHARA array
Cyril Pannetier, Philippe Berio, Denis Mourard +11
SPICA-FT is part of the CHARA/SPICA instrument which combines a visible 6T fibered instrument (SPICAVIS) with a H-band 6T fringe sensor. SPICA-FT is a pairwise ABCD integrated opti…
Building a GRAVITY+ Adaptive Optics Test Bench
The Gravity Plus Consortium, Florentin Millour, Philippe Berio +22
We present the testbench aimed at integrating the GRAVITY+ adaptive optics GPAO. It consists of two independent elements, one reproducing the Coud{é} focus of the telescope, includ…
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 diameters of interferometric calibrators with MATISSE
S. Robbe-Dubois, P. Cruzalèbes, Ph. Berio +16
A good knowledge of the angular diameters of stars used to calibrate the observables in stellar interferometry is fundamental. As the available precision for giant stars is worse t…
