in Orion Source I.
Looking at the star using NASA's Hubble Space Telescope, astronomers had expected to see a bipolar outflow
of twin lobes of gas from the star.
When the star later expels a fast wind, the wind rams into and is funneled by the older material, creating a bipolar outflow
Over the last 1,500 years, nearly one and a half times the mass of our Sun has been lost by the central star of the Boomerang Nebula in an ejection process known as a bipolar outflow
The new research focuses on HH 46/47, the bipolar outflow
from a protostar forming on the outskirts of the Gum Nebula, at about 1,400 light-years away.
Mapping the carbon monoxide, he found that the infrared source is the center of a bipolar outflow
of matter amounting to something between 1 and 10 times the mass of the sun per year.
The present project brings together the expertise of two research groups at MPIfR, infrared interferometry in order to investigate the structure of the disk and submillimeter astronomy showing the structure of the bipolar outflow
," he added.
t does so by spewing material in opposite directions as a bipolar outflow
Either turbulence within the nebula, or a phenomenon called bipolar outflow
from the early sun could account for the long-distance transport of cometary material, according to Simon and his co-authors.
At the same time, strong winds lift off from the inner disk regions and form a bipolar outflow
that burrows through the surrounding dark cloud, thus forming two large outflow cavities.
It ejects two streams of plasma in a bipolar outflow
at velocities of several hundred kilometers per second.
They display emission lines consistent with a bipolar outflow
and possibly represent incipient jets.
