Detection of HCO⁺ towards Cygnus OB2 No. 12.

Abstract (from CDS):

HCO⁺ has been detected for the first time towards the star Cygnus OB2 No. 12 through emission of the 1-0 rotational transition at 89GHz. The CO(J=2-1) transition has also been observed. The observations are consistent with a model of dense regions embedded in a low-density clump gas. If actually present, the dense component would have an aggregate size L≤1300au, in agreement with estimates of small-scale density fluctuations observed along diffuse lines of sight.
