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.

CHARA interferometry measures the red giant in T CrB at 0.70 mas (H-band) and 0.72 mas (K-band), giving a physical radius of 69-71 solar radii consistent with Roche lobe filling at the adopted distance.

Pre-nova Observations of T CrB: A view from the CHARA Array
CHARA interferometry measures the red giant in T CrB at 0.70 mas (H-band) and 0.72 mas (K-band), giving a physical radius of 69-71 solar radii consistent with Roche lobe filling at the adopted distance.
