Generative spectral decomposition on NEID solar data recovers 238 of 500 injected planets (including 13 with K<0.3 m/s) versus 9 for traditional CCF detrending in calibrated injection-recovery tests.
Solar image analysis shows typical astrometric jitter of 0.342 μas pc from activity, below the ~3 μas Earth-planet signal at 1 pc, so stellar contamination does not prevent Earth-like exoplanet astrometry around Sun-like stars.

Astrometric exoplanet detection survives solar-like stellar contamination
Solar image analysis shows typical astrometric jitter of 0.342 μas pc from activity, below the ~3 μas Earth-planet signal at 1 pc, so stellar contamination does not prevent Earth-like exoplanet astrometry around Sun-like stars.
