HR diagram of δ Scuti stars. The blue dots represent the location of the δ Scuti stars using the TIC parameters, while the red dots represent the subgroup of stars with spectroscopic values of Teff from LAMOST. The observational instability strip boundaries from Murphy et al. (2019) are shown as solid lines. The evolutionary tracks were computed using MESA v10108 with X = 0.71 and Z = 0.01.
