Granulation on a quiet K dwarf: HD 166620 I. Spectral signatures as a function of line-formation temperature

[2509.04573] Granulation on a quiet K dwarf: HD 166620 I. Spectral signatures as a function of line-formation temperature Skip to main content We gratefully acknowledge support from the Simons Foundation, member institutions , and all contributors.
By examining spectra and RVs as a function of line formation temperature , we investigated the sensitivity of granulation-induced RV variations across different photospheric layers.
