Abstract
We report the results of CO J=1→0 mapping of portions of the blue outflow lobe of L 1551 with ∼7″ (N-S)×4″ (E-W) resolution, obtained with the three-element OVRO millimeter array. Comparison of our interferometer mosaic with lower resolution single-dish data shows that we resolve the strongest single-dish emission regions into filamentary structures, such as are characteristic of shock fronts mapped via their near-infrared H 2 emission in other outflow sources. We detect a continuous velocity gradient across the brightest filamentary structure in our maps. The projected, deconvolved, FWHM of this feature is 1-2×10 16 cm, similar to that predicted in theoretical models of C-shocks
