DENSE CORES AND OUTFLOWS IN REGIONS OF HIGH MASS STAR FORMATION
Results of systematic studies of high mass star forming cores and associated high velocity outflows are reviewed. They are based on the surveys of these objects in CS, C18O, HNCO, SO and other molecular lines. Statistical distributions of the core parameters (mass, size, mean density, temperature, IR luminosity to mass ratio and velocity dispersion) are presented. The dependences of these parameters on galactocentric radius are analyzed. The frequency of occurrence and the basic properties of associated outflows (mass, momentum, kinetic energy) are derived. Their correlations with the bolometric luminosity of embedded IR sources are discussed.
