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…
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: 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…
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…
NIRPS tightens the mass estimate of GJ 3090 b and detects a planet near the stellar rotation period
Pierrot Lamontagne, Drew Weisserman, Charles Cadieux +148
We present an updated characterization of the planetary system orbiting the nearby M2 dwarf GJ 3090 (TOI-177; pc), based on new high-precision radial velocity (RV) observa…
NIRPS and TESS reveal a peculiar system around the M dwarf TOI-756: A transiting sub-Neptune and a cold eccentric giant
Léna Parc, François Bouchy, Neil J. Cook +148
The Near InfraRed Planet Searcher (NIRPS) joined HARPS on the 3.6-m ESO telescope at La Silla Observatory in April 2023, dedicating part of its Guaranteed Time Observations (GTO) p…
