Figure 12-1
-Refer to Figure 12-1. A Type I Cepheid has been located in an open cluster. The period of the Cepheid variable is 30 days and the variables apparent visual magnitude, m, is 10. First, use 12-1 to estimate the absolute visual magnitude, M . Calculate the distance to this open cluster? Hint: d_pc = 10⁽^m^-^M^{+ 5) /5}
