THE SPECTROPHOTOMETRY OF THE INFRARED LINES OF IONIZED CALCIUM LAMBDA 8498, 8542, 8662 IN FLOC CULI PART II. THE GENERAL CHARACTERISTIC PROP ERTIES OF INFRARED LINES IN THE SPECTRA OF FLOC CULI AND SPOTS,
Abstract
The general characteristic properties of the infrared triplet in the spectra of flocculi and spots are discussed. The spectra of flocculi were taken with the solar tower telescope of the observatory, with a dispersion of 0.35 A/mm. The photometric study of the spectrograms showed tthat bright reversals IR(2), similar to the bright reversals H(2) and K(2), and also dark lines IR(3), similar to the lines H(3) and K(3), are observed in the spectra of all sufficiently bright flocculi. The bright reversals IR(2) with the dark lines IR(3) are usually nonsymmetric. More often the bright reversal IR(2) is displaced towards shorter wavelengths, relative to its nor mal position, and the absorption IR(3) is dis placed towards longer wavelengths, relative to this emission. As it is known, this is also ob served for the lines H(2) and K(2), H(3), and K(3). The problem of the origin of the IR(3) lines is discussed. A preliminary discussion is given of the spectra of sunspots in the infrared triplet region. (Author)
