As a result, they estimate that only about 7.5 TW of power could be extracted from the jet stream, and that even this would have a major effect on climate (Earth System Dynamics, vol 2, p 201). (newscientist.com)
A dusty disk like that in TW Hydrae tends to emit radio waves with wavelengths similar to the size of the particles in the disk. (public.nrao.edu)
In TW Hydrae, the astronomers explained, both the relatively close distance of the system and the stage of the young star's evolution are just right to allow the relationship of particle size and wavelength to prevail. (public.nrao.edu)
