Current Research

COMPLETE Survey of Star-Forming Regions. Graduate student Helen Kirk and I are involved in this research. This project, begun in 2001, aims to fully sample the density structure in most of the molecular cloud complexes to be observed in the upcoming SIRTF Legacy project (From Molecular Cores to Planet Forming Disks) on scales from 500 AU to 10 pc. We have applied for long-term status at the JCMT to map, using SCUBA, the sub-millimetre dust emission of Serpens, Perseus, and Ophiuchus. In addition, the velocity structure of these regions will be mapped using spectral-line observations obtained with SEQUOIA at FCRAO.

JCMT Sub-Millimetre Observations of Star-Forming Regions. Currently John Bally and I are using SCUBA at 450 and 850 microns to survey the dense ridge of molecular gas located in the Orion A molecular cloud. A second project, in conjunction with the Canadian Consortium for the Study of Star-Forming Regions, is also scan-mapping a large sample of clouds.

Destruction of Circumstellar Disks around Young Stars. Together with Isamu Matsuyama, David Hollenbach, Norm Murray, and Lee Hartmann, I have been continuing to work on the many mechanisms through which a young star will lose its gaseous disk. The results of this research will have implications for the formation likelihood of planets around various types of stars, and in a variety of environments. I continue to be involved in projects to observe the various conditions within the evaporating disks, in collaboration with John Bally.
