Bipolar outflow
WebContext: The bipolar outflows associated with low-mass protostars create cavities in the infalling envelope. These cavities are illuminated by the central protostar and inner disk, creating a bipolar scattered light nebula at near-infrared and mid-infrared wavelengths. ... Starting in 2007, the surface brightnesses of the eastern and western ... WebAug 7, 2024 · The scattered-light nebula traced by mid-infrared observations and molecular outflow distribution do not necessarily match completely, as discussed by Tobin et al. and Tokuda et al. . Moreover, the bipolar feature of the newly detected wing components is hard to explain as an outflow lobe from another protostar.
