Title: The place of interferometry in massive star multiplicity studies ?

Authors: Hugues Sana & Jean-Baptiste Le Bouquin

Abstract: While it is well known that most, if not all, massive stars are found to be part of 
binary or multiple systems, a complete characterization of the properties of these multiple objects 
are still lacking. In the present talk, we will review the current status of the field, emphasizing 
the need of using complementarity techniques to address theses issues. We will describe what we 
think is the place of interferometry in this context. We will finally conclude by presenting a 
recently initiated project that matches the presented framework.
