Pollux is a high-resolution spectropolarimeter working from 100 nm to 1.6 microns proposed for HWO by a European consortium. Pollux will allow us to study stellar and (exo)planetary systems, as well as cosmic ecosystems. For example, Pollux will provide new insights on exoplanet formation and evolution, characterisation of the atmospheres and magnetospheres of stars and planets, and...
SHARP is a conceptual study for a near-IR (0.9-2.4 mu) spectrograph designed to exploit the capabilities of future ground-based AO-assisted Extremely Large Telescopes (ELTs) and space-based Habitable World Observatory (HWO). The instrument concept is driven by the goal of creating a spectrograph capable of tackling the most important questions in astrophysics and cosmology, from exploring...
