  We present a quantitative investigation of the effect of stellar oscillations
on Doppler velocity planet searches. Using data from four asteroseismological
observation campaigns, we find a power law relationship between the noise
impact of these oscillations on Doppler velocities and both the
luminosity-to-mass of the target stars, and observed integration times.
Including the impact of oscillation jitter should improve the quality of
Keplerian fits to Doppler velocity data. The scale of the effect these
oscillations have on Doppler velocity measurements is smaller than that
produced by stellar activity, but is most significant for giant and subgiant
stars, and at short integration times (i.e. less than a few minutes). Such
short observation times tend to be used only for very bright stars. However,
since it is these very same stars that tend to be targeted for the highest
precision observations, as planet searches probe to lower and lower planet
masses, oscillation noise for these stars can be significant and needs to be
accounted for in observing strategies.
