摘要：

We describe the ages of delta Scuti stars as a function of the fundamental period of pulsation. We show that the metal-poor variables (pulsating blue stragglers or SX Phe stars) should be restricted to short periods as observed. The metal-strong variables on the other hand, should show a much greater range of periods, but LogP >= -1.3 days.
