Very High Precision Astrometry for Exoplanets and Dark Matter with the Habitable Worlds Observatory

F. Malbet, J. Amiaux, F. Ardellier-Desages, E. Doumayrou et autres

Astrometry, one of the oldest branches of astronomy, has been revolutionized by missions like Hipparcos and especially Gaia, which mapped billions of stars with extraordinary precision. However, challenges such as detecting Earth-like exoplanets in nearby habitable zones and probing the influence of …
