Spectral line: A
dark or bright
line in a uniform and continuous spectrum.
At the same time, the new model itself is so general that it will offer an interesting starting point for the search for
dark matter even if it turns out that the
spectral line discovered in 2014 has a different origin.
A
spectral line is a
dark or bright
line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.
The solar spectrum of the sun consists of a roughly black body like thermal continuum spectrum, peaking at around 0.5 microns wavelength (plotted on wavelength scale; not wave number), and overlaid with the Fraunhoffer
lines of either bright atomic
spectral lines, due to elements in the sun, or
dark atomic absorption
lines, due to absorption of elements in the solar outer atmosphere.
