Large Interferometer For Exoplanets (LIFE): VIII. Detecting Rocky Exoplanets In The Habitable Zones Of Sun-like Stars
While previous studies have shown a strong preference for a future mid-infrared nulling interferometer space mission to detect habitable zone planets around M-dwarfs, we here focus on a more conservative […]
