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…
NuAncestor: an artificial satellite-borne star for accurate frequency calibration of ground-based EPRV spectrographs
F. Pepe, M. Bugatti, A. Baur +17
The accuracy of state-of-the-art Extreme Precision Radial Velocity (EPRV) spectrographs depends on the access to extremely precise and stable wavelength calibration sources. There…
The RISTRETTO simulator: Exoplanet reflected spectra
M. Bugatti, C. Lovis, F. Pepe +4
The upcoming Ristretto spectrograph is dedicated to the detection and analysis of exoplanetary atmospheres, with a primary focus on the temperate rocky world Proxima b. This scient…
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…
