Abstract

A key ingredient missing from current formation and evolution theories of massive stars, and of cluster evolution, is a robust binary fraction and the intrinsic distributions of orbital parameters. The VLT-FLAMES Tarantula Survey (VFTS), which targeted 800 O- and B- stars in 30 Dor, was designed to detect most massive binaries with periods <200 d: the observed O-type binary fraction is 35% (126 binaries). Using a radial velocity monitoring, we will now characterise the orbits of these systems, with the aim of obtaining the first measurements of the period, mass-ratio and eccentricity distributions of massive binaries in a dense and dynamically complex environment, in which conditions are closer to those in super-star-clusters observed beyond the Local Group. We will also constrain the orbital properties of the 18 identified B-supergiant binaries, including an interacting and a post-interaction system. These systems represent key benchmark cases for models of close binary evolution. (AU)
