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…
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…
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…
ANDES, the high-resolution spectrograph for the ELT: RIZ Spectrograph preliminary design
Bruno Chazelas, Yevgeniy Ivanisenko, Audrey Lanotte +44
We present here the preliminary design of the RIZ module, one of the visible spectrographs of the ANDES instrument 1. It is a fiber-fed high-resolution, high-stability spectrograph…
