Abstract :
[en] In the framework of the Gaia-ESO survey we have determined the fundamental parame- ters of a large number of B-type stars in the Galactic, young ope n cluster NGC 3293. The determination of the stellar parameters is based on medium- resolution spectra obtained with FLAMES/GIRAFFE at ESO-VLT. As a second step, we adopted the acc urate parameters to determine the chemical abundances of these hot stars. We pre sent a comparison of our results with those obtained by the ’VLT-FLAMES survey of massive sta rs’ (Evans et al. 2005). Our study increases the number of objects analysed and provides an extended view of this cluster.
