B stars population in the field of the Large Magellanic Cloud NGC2004: first results with VLT-FLAMES.
Résumé
This document presents our very first results on a part of the program: "A study of the Be phenomenon in young open Galactic and Magellanic clusters". It concerns the B stars population in the LMC NGC2004 cluster and its surrounding field observed with the VLT/FLAMES instrumentation with the GIRAFFE spectrograph, at low resolution, in MEDUSA mode. First observational results which concern the ratio $\frac{Be}{B+Be}$ , the nebulosities in the field and the discovery of spectrocopic binaries are presented.
