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…
Test of a 34 GHz EOM laser frequency comb at ESPRESSO
Tobias M. Schmidt, Ewelina Obrzud, François Bouchy +18
Laser frequency combs (LFCs) are a promising technology for wavelength calibration of astronomical high-resolution spectrographs requiring utmost accuracy and stability, since they…
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…
The Phase Induced Amplitude Apodizer and Nuller -- High transmission, high dispersion coronagraphy at 2λ/D
N. Blind, N. Restori, B . Chazelas +3
Context. Proxima Cen b is the prime target for the search of life around a nearby exoplanet by characterizing its atmosphere in reflected light. Due to the very high star/companion…
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…
