Abstract

We present the radial velocity planet search in moderately wide binaries with similar components (twins) ongoing at Telescopio Nazionale Galileo (TNG) using the Galileo High Resolution Spectrograph (Spettrografo Alta Risoluzione Galileo, SARG). We discuss the sample selection, the observing and analysis procedures, the main results of the radial velocity monitoring and the implications in terms of planet frequency in binary systems. We also briefly discuss the second major science goal of the SARG survey, the search for abundance anomalies caused by the ingestion of planetary material by the central star. Finally, we present some preliminary conclusions regarding the frequency of planets in binary systems.
