Trouble is, there *are* no stars with known oscillations on this sort of
time scale (except the Sun).

What freq/period is in question?

The region of greatest interest, I gather, is 0-5mHz (millihertz, not
megahertz), with the earlier reported detections based on radial velocity
generally around 1mHz (that is, a period of 10-20 minutes).
