Observations of DNC and DCO+ toward the ∫-shaped Filament and Starless Cores in the Orion Molecular Clouds

Although the deuterium fraction is known to be a powerful evolutionary tracer, its variation within individual molecular cloud cores is still poorly understood. The northern ∫-shaped filament and 20 individual starless cores in the Orion A and B clouds were mapped in the deuterated molecules of DNC...
