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…
Dust and Molecular Emission from the S235 Star Forming Region
Jeong-Eun Lee, Chadwick H. Young, Yancy L. Shirley +2
We present the results of a multi-faceted study of the high-mass star-forming region S235. With the CalTech Submillimeter Observatory (CSO), we have observed and/or mapped over fif…
Dust Continuum Observations of Massive Star Forming Regions
Kaisa E. Mueller, Yancy L. Shirley, Neal J. Evans +1
We have observed 51 high mass star forming cores associated with water masers at 350 micron. The spectral energy distributions (SEDs) and dust continuum normalized radial intensity…
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…
Tracing the Mass during Low-Mass Star Formation. II. Modelling the Submillimeter Emission from Pre-Protostellar Cores
Neal J. Evans, Jonathan M. C. Rawlings, Yancy L. Shirley +1
We have modeled the emission from dust in pre-protostellar cores, including a self-consistent calculation of the temperature distribution for each input density distribution. Model…
