Abstract: The formation of single sdB stars is an unresolved issue and the presence of close sub-stellar companions could explain the stellar envelope ejection near the tip of the RGB, that is needed to form an sdB star. In the last 6 years the first planets orbiting sdB stars were detected using different methods. In this article we will discuss these recent discoveries, review the different detection methods used, and present some preliminary results obtained with Harps-N, which allows to reach an unprecedented accuracy in radial velocity measurements.
