The diagnostic separates granulation-sensitive and stable lines in late-G and K dwarfs, with FeI lines showing lower velocity sensitivity than FeII as effective temperature decreases, making solar line selections non-portable.

Differentiable optical simulation models telescope jitter blurring and shows that two-dimensional jitter models avoid systematic bias in binary separation measurements for the TOLIMAN exoplanet mission.
Tentative evidence for a super-Jupiter at 15-100 AU or brown dwarf at 20-170 AU in 51 Pegasi from RV curvature, but the signal is likely driven by Lick/Hamilton instrument drift.

Sensitivity of spectral lines to granulation: from the Sun to K-type stars
