RISTRETTO: Assembly and Testing of the Seven-spaxel, High-resolution, Diffraction-limited Spectrograph
Leonie Hoerner, Bruno Chazelas, Nathanaël Restori +24
The RISTRETTO project aims at the direct detection of the reflected light of extra-solar planets to measure albedos and detect possible biosignatures, using the high-contrast / hig…
DD4AO control law for RISTRETTO: robustness, real-time performance, and on-sky validation with PAPYRUS
Isaac Dinis, Muskan Schinde, Nicolas Blind +11
This study presents DD4AO progress towards its implementation in the RISTRETTO instrument. DD4AO is a novel frequency-domain, data-driven controller for adaptive optics that levera…
NIRPS joining HARPS at ESO 3.6 m. On-sky performance and science objectives
Francois Bouchy, Rene Doyon, Francesco Pepe +131
The Near-InfraRed Planet Searcher (NIRPS) is a high-resolution, high-stability near-infrared (NIR) spectrograph equipped with an AO system. Installed on the ESO 3.6-m telescope, it…
RISTRETTO: Manufacturing of a single-mode visible high resolution spectrograph
Bruno Chazelas, Christophe Lovis, Nicolas Blind +13
The Spectrograph of the RISTRETTO instrument is now currently being manufactured. RISTETTO is an instrument designed to detect and characterize the reflected light of nearby exopla…
RISTRETTO: Seven Spaxels Single Mode Spectrograph Design
Bruno Chazelas, Christophe Lovis, Nicolas Blind +6
The RISTRETTO project is aiming to build an instrument that will detect the reflected light from close-by exoplanet. It is a two stage instrument: An extreme AO system in the visib…
RISTRETTO: coronagraph and AO designs enabling High Dispersion Coronagraphy at 2 lambda/D
N. Blind, B. Chazelas, J. Kühn +13
RISTRETTO is the evolution of the original idea of coupling the VLT instruments SPHERE and ESPRESSO, aiming at High Dispersion Coronagraphy. RISTRETTO is a visitor instrument that…
