Sph as a function of the surface rotation period, Prot for 867 main-sequence stars observed in short cadence by the Kepler mission. Red circles represent stars with detected oscillations, and black circles are stars without their detection. Dashed lines represent the minimum (bottom) and maximum (top) Sph corresponding to the Sun magnetic activity. Coloured rectangles delimit the sample at a rotation period of about 5 days: in the grey area most stars do not present detectable oscillations, while in the slow-rotation regime (red area) most stars present detectable oscillations.
