spectroscopic Hertzsprung-Russell diagram of the stars in the sample within 2500 pc with three or more available multi-epoch spectra. Green circles correspond to systems identified as SB1. The bottom and right subpanels show RV_pp against T_eff and log(ℒ/ℒ_⊙), respectively. The gray areas highlight the threshold limits for detection of SB1 systems (see Appendix D). The evolutionary tracks correspond to nonrotating Geneva models. The average T_eff of our proposed TAMS is shown with a dashed purple line.
