The p-mode frequencies vary with the activity cycle of the star. However, as observed in the Sun, these temporal variations present differences in amplitude, phase, and frequency among individual modes. Thus the frequency separations will be observed to vary with time. Then depending on the strength and at what epoch of the stellar cycle the p-mode frequencies are measured, different frequency separations will be returned. We discuss here these variations and their possible impact on the determination of the stellar parameters (radius, age, and mass) in stars with solar-like oscillations.
