Constraining Proxima b’s atmosphere, orbit and albedo with RISTRETTO

What new methods can be employed to help astronomers distinguish the light from an exoplanet and its host star so the former’s atmosphere can be better explored? This is what a recent study accepted to Astronomy & Astrophysics and currently available on the arXiv preprint server hopes to address as an international team of researchers investigated how a novel and proposed telescopic instrument that could be capable of characterizing exoplanet atmospheres in new and exciting ways.
