The Chemistry of Dark Clouds: New Astrochemical Tools for Star Formation Studies
Edwin A. Bergin
The past decade has led to significant improvements in our understanding of the physical structure of the molecular cores of cold dark clouds. Observational efforts, in combination…
Sensitive Limits on the Water Abundance in Cold Low Mass Molecular Cores
Edwin A. Bergin, Ronald L. Snell
We present SWAS observations of water vapor in two cold star-less clouds, B68 and Core D in rho Ophiuchus. Sensitive non-detections of the 1(10)-1(01) transition of o-H2O are repor…
A Survey of 557 GHz Water Vapor Emission in the NGC 1333 Molecular Cloud
Edwin A. Bergin, Michael J. Kaufman, Gary J. Melnick +2
Using NASA's Submillimeter Wave Astronomy Satellite (SWAS) we have examined the production of water in quiescent and shocked molecular gas through a survey of the 556.936 GHz trans…
Abundances of Molecular Species in Barnard 68
James Di Francesco, Michiel R. Hogerheijde, William J. Welch +1
Abundances for 5 molecules (C18O, CS, NH3, H2CO, and C3H2) and 1 molecular ion (N2H+) and upper limits for the abundances of 1 molecule (13CO) and 1 molecular ion (HCO+) are derive…
N2H+ and C18O Depletion in a Cold Dark Cloud
Edwin A. Bergin, Joao Alves, Tracy L. Huard +1
We present sensitive, high angular resolution molecular-line observations of C18O and N2H+ toward the dark globule B68. We directly compare these data with the near-infrared extinc…
