Instrumentation on The Second Earth Initiative Spectrograph

The Second Earth Initiative Spectrograph (2ES) is a next-generation, fiber-fed, high-resolution and extreme-precision radial velocity (RV) spectrograph. 2ES will be installed on the 2.2m ESO/MPG telescope on La Silla, Chile, and dedicated to a >5 year observing program with access to the majority (2/3) of the telescope time. Its goal is to discover temperate terrestrial Earth-mass planets in the habitable zone around bright solar-type stars.
To achieve this goal, 2ES aims for ultra-high instrumental radial-velocity precision (≈10 cm/s) and an observing strategy that involves high-cadence observation of the brightest Sun-like stars in the Southern Hemisphere.
The discovery of such planets will be exceptionally valuable due to their proximity to our Solar System, because they will, in perpetuity, be the best targets for next-generation flagship observatories with the aim of detecting biosignatures in their atmospheres, like the Habitable Worlds Observatory (HWO).
