Seismic Hertzsprung-Russell diagram, where the luminosity is modified by the mean large frequency spacing, Δν. The colored symbols represent the stars studied here: red triangles are the main sequence stars; blue stars are stars near the TAMS; orange squares are subgiants. The Kepler sample with detected solar-like oscillations (Mathur et al. 2022) are also represented with gray circles. The evolutionary tracks with solar metallicity from the Aarhus STellar Evolution Code (Christensen-Dalsgaard 2008a) are represented with the black lines. The average uncertainties on T_eff and Δν are shown in the lower left corner.
