Abstract:
We observed the clustered star forming complex NGC 1333 with the BIMA
and FCRAO telescopes in the transitions HCO+(1-0) and N2H+(1-0) over
an area with resolution ∼10" (0.015pc). The N2H+ emission follows
very closely the submillimeter dust continuum emission, while HCO+
emission appears more spatially extended and also traces outflows. We
have identified 93 N2H+ cores using the CLUMPFIND algorithm, and we
derive N2H+ core masses between 0.05 and 2.5M☉ , with
uncertainties of a factor of a few, dominated by the adopted N2H+
abundance.
Description:
Observations of NGC 1333 were made with the 10-element Berkeley
Illinois Maryland Association (BIMA) interferometer, at Hat Creek, CA,
operating simultaneously at 89 and 93GHz. The field was divided into
two halves, with the southern half observed mostly in the fall of
2001, and the northern half observed in the spring of 2002.
