Abstract: We present the intrinsic radial velocity limits obtained from two different asteroseismological campaigns performed with SARG, the high resolution spectrograph of the TNG (Telescopio Nazionale Galileo). The nightly averages show rms dispersion of just 0.2 m/s over one week. This allows us to exclude short period planets of a few Earth masses around these stars.
