Abstract

The VLT-FLAMES Tarantula Survey offers a unique opportunity to study the stellar and gas kinematics of 30 Doradus in the Large Magellanic Cloud (LMC). Using the nebular emission lines in the fibre spectra of ~1000 stars, we can map the radial velocity structure of ionized gas across the 30 Doradus region, enabling us to study the environment of massive stars. Multi-epoch ARGUS-IFU observations and MEDUSA/UVES fibre spectroscopy in the young massive cluster R136, at the core of 30 Dor, will allow us to quantify the effect of binaries on the velocity dispersion of the cluster. The true velocity dispersion will be measured from the radial velocities of the identified single stars, providing an essential ingredient to estimate the dynamical mass and probe the dynamical state of R136.
