THE PLACE OF INTERFEROMETRY IN MASSIVE STAR MULTIPLICITY STUDIES

While it is well known that most massive stars are found to be part of binary or multiple systems, an accurate characterization of the statistical properties of these multiple objects is still lacking. In the present talk, we will review the current status of the field, emphasizing the need of using complementarity techniques to cover the large parameter space. We will also describe what we think is the place of interferometry in this context.3 pages, 3 figures, to appears in the conference proceedings "The interferometric view of hot stars (2009)"status: publishe
