In preparation for the ESA PLATO mission, spectroscopy data coupled with data from Gaia have an important role in building up a detailed knowledge of the bright star sample that will be targeted by PLATO. Detailed chemical analysis studies of exoplanet host stars have been used to infer that low metallicity stars that host exoplanets have an overabundance of alpha- elements. Precise chemical determinations of the host stars of exoplanets can potentially be used to statistically infer the makeup of their orbiting planets (terrestrial-like, gas-dwarf planets or gas giant planets). However, recent studies are revealing a range of subtle and sometimes conflicting results and trends (e.g. lack of clear correlations between stellar metallicity and planetary residual metallicity that would be predicted from Giant planet formation models). Comprehensive studies in twilight time survey of bright...
