Determining the cosmic ray ionization rate in dynamically evolving clouds
C. J. Lintott, J. M. C. Rawlings
The ionization fraction is an important factor in determining the chemical and physical evolution of star forming regions. In the dense, dark starless cores of such objects, the io…
Molecular Clouds as Ensembles of Transient Cores
R. T. Garrod, D. A. Williams, J. M. C. Rawlings
We construct models of molecular clouds that are considered as ensembles of transient cores. Each core is assumed to develop in the background gas of the cloud, grow to high densit…
Modeling the Physical Structure of the Low Density Pre-protostellar Core Lynds 1498
Yancy L. Shirley, Miranda K. Nordhaus, Jana M. Grcevich +3
Lynds 1498 is a pre-protostellar core (PPC) and was one of the initial objects toward which molecular depletion and differentiation was detected. Despite the considerable scrutiny…
Hot Cores : Probes of High-Redshift Galaxies
C. J. Lintott, S. Viti, D. A. Williams +2
The very high rates of second generation star formation detected and inferred in high redshift objects should be accompanied by intense millimetre-wave emission from hot core molec…
B335: A Laboratory for Astrochemistry in a Collapsing Cloud
Neal J. Evans, Jeong-Eun Lee, Jonathan M. C. Rawlings +1
We present observations of 25 transitions of 17 isotopologues of 9 molecules toward B335. With a goal of constraining chemical models of collapsing clouds, we compare our observati…
