The spectrum of short-period light variations of delta Sct-type star SS Psc.
In Delta Sct-type stars with a large pulsation amplitude, a wide spectrum of short-period nonstable light oscillations has been detected in addition to the primary period light variations. The amplitude of these oscillations does not exceed 0.05 m, and increases toward the UV. Variations in (B - V) and (U - B) occur in the antiphase. The phase of the oscillations remains stable after the resumption of the variations after 10-25 days.
