The λ-Orionis ring in CO.

Abstract (from CDS):

The results of a new CO(J=1->0) survey of the ring of molecular clouds around the HII region Sh-2-264 and the λ-Orionis OB-association are presented. The distribution of molecular gas closely approximates that of the dust seen in IRAS emission. The total molecular mass is 1.4x104M☉. The mass spectrum of the emission clumps is a power-law with index -1.8, similar to that observed in other star-forming regions. The kinematics of the ring are modelled, but its alignment close to the plane of the sky allows only very weak constraints on expansion velocity and the age of the system. The data are compared with previous surveys, and possible evolutionary schemes for the region discussed.
