Possible origins for the 12 microns emission lines in the solar spectrum
Abstract
The detection of about 40 unidentified emission lines near a wavelength of 12 microns in the solar spectrum has been reported by Braut and Noyes (1982, 1983). Braut and Noyes point out that these lines are a potentially powerful tool for magnetic field measurements in stars. It appears that the great widths of the absorption features in the strongest lines offer probably a strong clue to their identifications. The present investigation is concerned with two possible sources for the line broadening taking into account abundance broadening and autoionization.
