CHARA/SPICA: The six-telescope visible combiner and near-infrared fringe tracker for the CHARA Array
D. Mourard, P. Bério, C. Bailet +43
The suite called Stellar Parameters and Images with a Cophased Array (SPICA) has two interferometric instruments installed at the focus of the CHARA Array located at Mount Wilson,…
ANDES, the high-resolution spectrograph of the ELT: simulated performance of the CORO module and overview of the high-contrast capabilities for exoplanet observations
M. N'Diaye, A. Simonnin, A. Spang +19
We present the simulated performance of the coronagraph (CORO) module for ANDES, the Extremely Large Telescope (ELT) high-resolution spectrograph. ANDES aims to address a broad ran…
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…
GRAVITY+ adaptive optics (GPAO) tests in Europe
Florentin Millour, Guillaume Bourdarot, Jean-Baptiste Le Bouquin +54
We present in this proceeding the results of the test phase of the GRAVITY+ adaptive optics. This extreme AO will enable both high-dynamic range observations of faint companions (i…
Cascade adaptive optics with a second stage based on a Zernike wavefront sensor for exoplanet observations
M. N'Diaye, A. Vigan, B. Engler +7
Over the past decade, the high-contrast observation of disks and gas giant planets around nearby stars has been made possible on ground-based instruments using extreme adaptive opt…
ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
Exoplanet imaging with ELTs: exploring a second-stage AO with a Zernike wavefront sensor on the ESO/GHOST testbed
Mamadou N'Diaye, Arthur Vigan, Byron Engler +6
We propose to explore a cascade extreme Adaptive optics (ExAO) approach with a second stage based on a Zernike wavefront sensor (ZWFS) for exoplanet imaging and spectroscopy. Most…
The GRAVITY+ Project: Towards All-sky, Faint-Science, High-Contrast Near-Infrared Interferometry at the VLTI
GRAVITY+ Collaboration, :, Roberto Abuter +134
The GRAVITY instrument has been revolutionary for near-infrared interferometry by pushing sensitivity and precision to previously unknown limits. With the upgrade of GRAVITY and th…
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…
MATISSE, the VLTI mid-infrared imaging spectro-interferometer
