Fig. 2


Intensity integrated maps (contours) of c-C3H2, C2H, DCO+, and continuum toward IRAS 16293−2422. Intensity integrated H2CO 5–4 (0–60 km s−1) is shown in color scale. Contours show the respective lines in steps of 2, 3, 5, 20, and 60σ, with σ (Jy beam−1 km s−1) indicated in the lower right of each panel. For continuum at 870 μm, the levels arelogarithmically spaced between 0.02 and 2 Jy beam−1, and highlight the ridge that spans between sources A and B. The positions of IRAS 16293−2422 A and B are indicated with a star and circle, respectively. The gray arrows indicate the outflow directions, while the cyan ellipse shows the disk-like structure. The green circle on the bottom left panel indicates the beam of the combined 12 m and ACA observations. For the c-C3 H2 and C2H panels, theemission centered on A is contamination from other molecule(s) and is masked out in a radius of 2′′ from the position of A.
