A CS J = 5 -> 4 Mapping Survey Towards High Mass Star Forming Cores Associated with H2O Masers

Abstract

In this survey we have systematically mapped 63 cloud cores in the CS J = 5 -> 4 line towards a sample of high mass star forming cores with water masers (Plume et al. 1992, Plume et al. 1997) using the CSO. From the CS spectra and maps we determine cloud core sizes, virial masses, a mass spectrum, and a size-linewidth relationship.
