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 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…
