| A photoelectric study of three southern Delta Scuti stars
Differential photoelectric observations of three Delta Scuti stars AIScl, WZ Scl, and XX Scl were obtained on ten nights during October 1978.Al Scl did not exhibit strictly periodic behavior, but showed a tendencyto pulsate at 134 minutes. WZ Scl and XX Scl were both found to bemultiperiodic, with period ratios of 0.6853 and 0.9522, respectively. Asthe period for radial fundamental and first overtone pulsation is 0.76,the observed period ratios are interpreted as caused by nonradialpulsation. A slightly modified Jurkevich period search method, used toobtain these results, is described.
