Notes

In Bonanos et al. (2003), a variable red star, M31 J004433.7+414403.0, is reported, tentatively classified as a Type II Cepheid. According to Mikołajewska et al. (2014), this star may be M31SyS J004433.74+414402.8, and the 34-day periodicity would then reflect an SR pulsation of the red component.
