英文摘要: Using a non-local time-dependent statistical theory of convection, we made a linear pulsational instability analysis for stars in the mass range 1.4-3.0 M-circle dot. The results define a red edge for the delta Scuti instability strip, which fits the observational boundary very well. It is found that the dynamic coupling between convection and oscillation together with the turbulent viscosity are the two main damping mechanisms for low-temperature stars.
