Sentences with phrase «bipolar outflow»
A "bipolar outflow" refers to the simultaneous ejection of material in opposite directions from a central source, often seen in astronomical phenomena like stars or protostars. It occurs when high-speed streams of gas and dust are expelled from both the top and bottom, typically resembling a bipolar or two-sided structure. Full definition
What was even more confusing was that the jets did not seem to carry nearly enough matter or force to create the massive bipolar outflows.

Jets of matter seem to squirt in opposite directions along the rotational poles of the star (or disk) and sweep up the ambient matter in two lobes of outwardly moving molecular gas — the so - called bipolar outflows.
The most natural one was also the most obvious: that the jets were somehow powering the much larger, and much more distant, bipolar outflows.
Although these bipolar outflows were moving much more slowly than the HH objects — about 10 miles per second — they were 10 times as massive as the jets, with a volume many times larger.
A subset of this population has bipolar outflows that align to the star's rotation axis.
Astronomers using NASA's Hubble Space Telescope had expected to see a bipolar outflow of twin lobes of gas from the star, perhaps similar to those emanating from the massive... Read more
«This is exactly the signature we knew we would get if this was a bipolar outflow,» explained Rongmon Bordoloi of the Space Telescope Science Institute, a co-author on the science paper.
The clouds are also not explained by a bipolar outflow from a protostar.
Such jets and bipolar outflows are doubly interesting because their counterparts were discovered sometime earlier on a fantastically larger scale in the double - lobed forms of extragalactic radio sources, such as quasars.
Such enormous kinetic energy may be produced by an interaction with a supernova explosion or a bipolar outflow form a bright massive protostar.
The team observed the launching point of a bipolar outflow, and found a cluster of vibrationally excited SiO masers tracing an outflow arising from the surface of the disk.
