OBSERVATIONS OF MOLECULAR OUTFLOW IN CAR 291.6-01.9
Description
We report the first observations of a dense molecular gas nebula and bipolar outflow in Car 291.6-01.9, showing characteristics of an embedded young stellar object (YSO). Using the Mopra radio telescope near Coonabarabaran, Australia, we image the kinematic structure of several emission features to examine physical properties within a molecular clump of mass ∼3.2 ± 0.6 × 103 M☉ in which a stellar cluster may be forming. Motivated by acquiring a more thorough understanding of star formation we ask what may have initiated collapse in the clump; observed outflow alignment is suggestive of ∼1.0 pc distant massive star HD 308280 radiative-driven compression as a formation trigger for the dense core. An outflow derived age of <106 years, together with significant C18O and SO core depletion, support the case for the core as the host of an extremely YSO cluster.
