Wolf-Rayet stars in the Magellanic clouds. VI: Spectroscopic orbits of WC binaries and implications for W-R evolution

In addition to obtaining spectroscopic orbits for the three largest WC + O binary systems in the LMC, an improved orbit has been determined for the SMC's bright WO + O system. The very short periods noted in two of the LMC binary systems indicate that orbital angular momentum must have been los...
