Abstract
ANDES is an optical and near-infrared high-resolution spectrograph for the European Extremely Large Telescope, currently undergoing Phase B. ANDES main science case is the study of small, rocky exoplanet atmospheres, including the potential for biomarker detections, and the ability to reach this science case is driving its instrumental design. ANDES will be a powerful transformational instrument for exoplanet science, allowing not only an exquisite determination of atmospheric composition, but also the study of isotopic compositions, dynamics and weather patterns, mapping the planetary atmospheres and probing atmospheric formation and evolution models. Moreover, ANDES will be able to probe the atmospheres of planets in reflected light. In particular, we show how ANDES will be able to unlock the atmospheres of a golden sample of nearby non-transiting habitable zone planets with only a few tenths of nights. A scientific objective that no other currently approved astronomical facility will be able to reach.
