ALMA Band 3 intensity integrated map of HC₃N 10–9. The 3σ level is indicated on the colorbar with a horizontal white line, with σ = 0.01 Jy beam⁻¹ km s⁻¹. The positions of IRAS 16293 A and B are marked with a white star and filled circle, respectively. The dashed orange lines highlight the structures identified in this work. The arrows indicate the E–W (green) and NW–SE (red) outflow directions from source A. The white ellipse in the bottom-right corner indicates the synthesized beam.
