Optical spectroscopy of X-Mega targets : II. The massive double-lined O-type binary HD93205

A new high-quality set of orbital parameters for the O-type spectroscopic binary HD 93205 has been obtained combining échelle and coudé CCD observations. The radial velocity orbits derived from the He iiλ4686 Å (primary component) and He iλ4471 Å (secondary component) absorption lines yield semi-amp...
