Simoda, M., and I. Iben, Jr., 1968: Heavy-element abundances and the interpretation of globular cluster characteristics. Astrophys. J., 152, 509-513, doi:10.1086/149567.
A grid of evolutionary models has been constructed for all permutations of the composition parameters Y = 0.35, 0.20, 0.10, 0.0 and Z = 10-3, (5/3)×10-4, 10-5. Using time-constant loci derived from this grid, a relationship is established between cluster age, initial composition of cluster stars, and the luminosity of stars near cluster turnoff. It is found that a variation in Z by a factor of 5 can affect the determination of cluster age by as much as a variation in Y from 0.35 to 0.10.
