Hertzsprung–Russell diagrams of solar-like stars with temperatures from spectroscopy and predicted luminosities from asteroseismic modeling. The panels are arranged by metallicity, with the lines showing theoretical evolutionary sequences for stars of the corresponding metallicities having the indicated masses (expressed in solar units). The dashed line traces the zero-age main sequence. The background colors indicate the spectral types of the stars (F, G, K). Typical uncertainties are 0.15 L_⊙ and 100 K.
