Resumen:
Making use of the multiplexing facilities of Gemini Multi Object Spectrograph (GMOS) we were able to investigate the presence of binary stars within the ionising cluster of 30 Doradus. This issue turns out to be crucial to analyse the impact that the orbital motions within a spectroscopic pair can have on the stellar velocity dispersion measured in a single snapshot and consequently on the dynamic mass determination.
