Kinematics of F to M supergiants in the 30 Dor and Shapley II regions of the Large Magellanic Cloud

Accurate radial velocities have been obtained with the CORAVEL photoelectric scanner at ESO, La Siila, for 36 F-M supergiants in the 30 Dor and Shapley II regions of the LMC (5(h)20(m) < RA(2000) < 5(h)50(m), -70degrees09' < Dec (2000) < -68degrees30'). On the basis of these data, we revisit the content and spatial extent of the four kinematical groups of F-M supergiants discovered in this area by Prevot et al. 1989. Each is the oldest part of a larger star forming region, recognized by young HII regions or CO clouds, and/or a surrounding Halpha + [NII] superbubble. We discuss various gas tracers including the interstellar sodium and calcium lines.
