This result suggests that evolved stars destroy/engulf close-in planets during the red giant phase.\n  Aims: We are conducting a radial velocity survey of 164 bright G and K giant stars in the southern hemisphere with the aim of studying the effect of the host star evolution on the inner structure of planetary systems.
