The "E-corona" is the component of the corona with an emission-line spectrum, either inside or outside the wavelength band of visible light. It is a phenomenon of the ion component of the plasma, as individual ions are excited by collision with other ions or electrons, or by absorption of ultraviolet light from the Sun.
Chaos Corona is a computer-generated imagery 3D rendering software developed by Chaos Czech, a subsidiary of Chaos. It was created by Ondřej Karlík as a student project in 2009 and was developed by a Prague -based company Render Legion under the name Corona Renderer .
Coronagraph instruments are extreme examples of stray light rejection and precise photometry because the total brightness from the solar corona is less than one-millionth the brightness of the Sun. The apparent surface brightness is even fainter because, in addition to delivering less total light, the corona has a much greater apparent size ...
C2 - a white light coronagraph imaging from 1.5 to 6 solar radii (orange) C3 - a white light coronagraph imaging from 3.7 to 30 solar radii (blue) The first principal investigator was Dr. Guenter Brueckner. These coronagraphs monitor the solar corona by using an optical system to create, in effect, an artificial solar eclipse. The white light ...
The white-light emissions of helmet streamers is due to the high electron density of the confined plasma relative to the surrounding corona. Light from the photosphere is Thomson scattered off of these electrons with the intensity of scattered light depending on the number of electrons along the observer's line of sight.
The cause for this is unknown, but thought possibly due to ejection of dust that obscured the star's light. [ 6 ] Theta Coronae Borealis B is a white main sequence star of spectral type A2V that is around 2.5 times as massive as the Sun and located 86 astronomical units from the primary star, the two stars taking an estimated 300 years to orbit ...

The Illuminating Engineering Society (IES), is an industry-backed, not-for-profit, learned society that was founded in New York City on January 10, 1906. [ 1 ] [ 3 ] The IES's stated mission is "to improve the lighted environment by bringing together those with lighting knowledge and by translating that knowledge into actions that benefit the ...
