DD4AO control law for RISTRETTO: robustness, real-time performance, and on-sky validation with PAPYRUS
Isaac Dinis, Muskan Schinde, Nicolas Blind +11
The paper presents the DD4AO frequency‑domain, data‑driven adaptive optics controller, its implementation in the RISTRETTO instrument, and on‑sky validation with the PAPYRUS system…
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…
RISTRETTO: the PIAA Nuller in the prototyping phase
N. Restori, N. Blind, J. Kühn +6
The objective of the coronagraphic IFU of RISTRETTO is to enable High Dispersion Coronagraphy of planets at a distance of 2/D from their star, without compromising on transmiss…
RISTRETTO: a VLT XAO design to reach Proxima Cen b in the visible
N. Blind, M. Shinde, I. Dinis +10
RISTRETTO is the evolution of the original idea of coupling the VLT instruments SPHERE and ESPRESSO \cite{lovis_2016a}, aiming at High Dispersion Coronagraphy. RISTRETTO is a visit…
RISTRETTO: reflected-light exoplanet spectroscopy at the diffraction limit of the VLT
Christophe Lovis, Nicolas Blind, Bruno Chazelas +28
RISTRETTO is a visible high-resolution spectrograph fed by an extreme adaptive optics (AO) system, to be proposed as a visitor instrument on ESO VLT. The main science goal of RISTR…
