A frequency analysis of new observations of the rapidly oscillating Ap star HD 134214

Twenty-six hours of new high-speed photometric observations of HD 134214 obtained in 1990 and 13 hours obtained in 1985 from both the South African Astronomical Observatory and Lowell Observatory are presented. This star seems to pulsate with only one detectable frequency with a semi-amplitude of AB = 3.3 mmag. However, the 1985 data cannot be phased together with a single frequency, indicating that unknown complexities affect the light variations. We point out that HD 134214 is an excellent candidate star in which to search for evolutionary frequency change. (author)
