Bipolar outflow
WebThe flow of material in two opposing directions away from a central source, usually a star. Most young stars go through a violent phase of ejecting material. In some, jets are seen … WebApr 4, 2024 · The observations revealed that the red-shifted lobes of the CO (J=2 1) outflows of L1448--C (N) and L1448--C (S) are colliding. As a result of this interaction, the L1448-C (S) lobe seems to be truncated. The collision of the molecular outflows is also hinted by the SiO (J= 5 4) emission, where the velocity dispersion increases significantly …
