摘要：
The hk index has been used as a metallicity indicator for RR Lyrae variable stars. It is now being applied to the shorter period delta Scuti variables. Employing spectroscopic abundances of stars with published hk values and photometric indices calculated from stellar atmosphere models, a three-dimensional interpolation is used to determine [Fe/H] from intrinsic b-y, c(1), and hk values. The resulting [Fe/H], log g, and T-eff values for 10 delta Scuti stars are presented.
