CO J=2-1 observations of southern galactic plane HII regions

White, G. J. and Phillips, J. P. (1982). CO J=2-1 observations of southern galactic plane HII regions. In: Symposium on Neutral Clouds near HII Regions - Dynamics and Photochemistry, 24-26 Jun 1981, Penticton, British Columbia, Canada, pp. 231–236.



An attempt was made to extend previous southern CO observations and to search for objects exhibiting rotation, wide linewidths, or self-absorption; the presence of these effects in molecular spectra is very useful for modeling the thermal and dynamical structures of these star formation regions. The present survey was biased toward objects exhibiting recent star formation activity, indicated by the presence of interstellar water-vapor maser sources. Observations were made with the 2.5-m du Pont telescope of the Las Campanas Observatory. Particular attention is given to RCW 38 and the Carina Nebula.
