CS J = 7 -> 6 Mapping of Massive Star Formation Regions Associated with Water Masers
Claudia Knez, Yancy L. Shirley, Neal J. Evans +1
Twenty-four cores have been mapped in CS J = 7 -> 6 at the CSO. From the spectra we determine core sizes and virial masses. Combining results from the CS and dust continuum studies…

Early Phases and Initial Conditions for Massive Star Formation
Neal J. Evans, Yancy L. Shirley, Kaisa E. Mueller +1
Our knowledge of the initial conditions and early stages of high mass star formation is very limited. We will review recent surveys of regions in the early stages of massive star f…

A CS J = 5 -> 4 Mapping Survey Towards High Mass Star Forming Cores Associated with H2O Masers
Yancy L. Shirley, Neal J. Evans, Kaisa E. Mueller +2
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 e…
