Description
GaiaNIR has the potential to significantly advance exoplanet science. By extending high-precision astrometry to cooler and more obscured stars, it would broaden the range of both stellar and planetary environments accessible to astrometric planet detection. Combined with Gaia, this new instrument would provide a decades-long astrometric baseline, enabling the discovery and mass measurement of long-period giant planets that other methods cannot access, enabling thereby the detection of Solar-System analogues. Improved stellar parameters from GaiaNIR would enhance the characterization of known exoplanets and strengthen synergies with missions such as PLATO, Ariel, and JWST. GaiaNIR would thus play a central role in shaping future exoplanet studies.
