Description
We aim to further constrain the properties and evolutionary stages of dense cores in Orion B9. The central part of Orion B9 was mapped at 350 micron with APEX/SABOCA. A sample of nine cores in the region were observed in C^17^O(2-1), H^13^CO^+^(4-3) (towards 3 sources), DCO^+^(4-3), N_2_H^+^(3-2), and N_2_D^+^(3-2) with APEX/SHFI. These data are used in conjunction with our previous APEX/LABOCA 870-micron dust continuum data. Many of the LABOCA cores show evidence of substructure in the higher-resolution SABOCA image.
