H-R diagram of our sample of Be stars. Each star is identified with its sequence number, “No”, given in Table 1. The cross and filled circle symbols are for stars non-corrected and corrected from the rotation, respectively. The β Cephei (thick red curve) and SPB (thick blue curve) domains calculated by Miglio et al. (2007) with the OP opacity table and the AGS05+Ne chemical abundances are shown. The pink curves represent the evolutionary tracks of rotating stars with various solar masses calculated for by Georgy et al. (2013).
