A bipolar outflow comprises two continuous flows of gas from the poles of a star. Bipolar outflows may be associated with protostars (young, forming stars), or with evolved post-AGB stars (often in the form of bipolar nebulae). See more In the case of a young star, the bipolar outflow is driven by a dense, collimated jet. These astrophysical jets are narrower than the outflow and very difficult to observe directly. However, supersonic shock fronts along … See more Massive galactic molecular outflows may have the physical conditions such as high gas densities to form stars.

WebWe report the discovery of a collimated bipolar outflow emerging from a visible disk around the proto-planetary nebula IRAS 17106-3046. The radius of the disk, estimated to be 2500 AU at a distance of 4 kpc, is too large for it to be a Keplerian disk created by accretion. The radial intensity profile of the disk suggests that it is consistent ... WebBipolar outflows are often found in dense, dark clouds. They tend to be associated with the very youngest stars (ages less than 10,000 years) and are closely related to the molecular bow shocks. Indeed, the bow shocks are thought to sweep up or "entrain" dense gas from the surrounding cloud to form the bipolar outflow.

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 … WebIntroduction: Standard unipolar radiofrequency ablation (RFA) is typically successful in eliminating premature ventricular contractions (PVCs) originating from the ventricular outflow tract region. In a minority of cases, this approach may be ineffective. We report 4 cases where bipolar RFA was attempted after failed unipolar RFA.
