Context. We are carrying out a search for planets around a sample of solar twin stars using the HARPS spectrograph. The goal of this project is to exploit the advantage offered by solar twins to obtain chemical abundances of unmatched precision. This survey will enable new studies of the stellar composition - planet connection.Aims. We determine the fundamental parameters of the 88 solar twin stars that have been chosen as targets for our experiment.Methods. We used the MIKE spectrograph on the...[Show more]
