Abstract (from CDS):

Since 1995, the extra-solar planet search has driven the high resolution spectroscopy community to build more and more stable spectrographs in order to reach the photon statistics limit in radial velocity measurements. This situation opened the possibility of asteroseismic observations of stellar p mode pulsations in solar-like stars. In this contribution we summarize the high precision radial velocity measurements of two solar type stars (αCMi and µHer) using the SARG spectrograph at TNG equipped with an iodine cell. The analyzed spectra show individual measurement errors of about 1.0 m/s (very close to the theoretical photon noise limit). Further we discuss the synergy between high precision radial velocity asteroseismology campaigns and the search for Super Earths.
