Highly deuterated pre-stellar cores in a high-mass star formation region.

Abstract (from CDS):

We have observed the deuterated gas in the high-mass star formation region IRAS 05345+3157 at high-angular resolution, in order to determine the morphology and the nature of this gas. We have mapped the N2H+ (1-0) line with the Plateau de Bure Interferometer, and the N2D+ (3-2) and N2H+ (3-2) lines with the Submillimeter Array. We have detected two condensations in N2D+, with masses of ∼2-3 and ∼9M and diameters of 0.05 and 0.09pc, respectively. The high deuterium fractionation (∼0.1) and the line parameters of the N2D+ condensations indicate that they are probably low- to intermediate-mass pre-stellar cores, even though other scenarios are possible.
