Bipolar outflow
WebJul 4, 2024 · The 484 GHz Si 18 O line clearly traces a northeast–southwest bipolar outflow, although the size of the outflow lobes, ∼ 200 au, are much smaller than that … 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.

WebJan 24, 2016 · The cores are also dark at far infrared wavelengths up to ~100 microns. We detect 12CO(2-1) from a narrow, highly-collimated bipolar outflow that is being … WebAbstract. Approximately one-half of the L1551 bipolar outflow was mapped in the J = 1-0 transition of (C-12)O using the FCRAO 14 m telescope. The data were obtained by heavily oversampling over the beam area and then were reconstructed using a maximum entropy algorithm to obtain images of the high-velocity gas with an angular resolution of about 20 …

Both were deemed not medically fit for ECT, and were, instead, treated with intravenous (IV) ketamine. Both responded with a resolution of symptoms, returning to baseline level of … WebDefinition. Bipolar flows are a phenomenon associated with young stars still embedded in their parent molecular clouds. There are two kinds of flows – jets and molecular outflows. …
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 … WebBipolar Outflow - Relatively narrow beams of matter ejected in opposite directions by a protostar Black Hole - A region of space from which no matter or radiation can escape.

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.
