Fig. 5

Examples of variability of line profiles originating in the circumstellar matter in the yellow and red parts of the spectra of HD 112244. Left panels show the diffuse interstellar band at 5797.0 Å, the C iv 5801.3 and 5812.0 Å, and the He i 5875.7 Å line profiles, while the right panels show Hα, the diffuse interstellar 6613.6 Å band and the He i 6678.2 Å and He ii 6683 Å line profiles for the same spectra. The upper panels illustrate the variability on a time scale of days and the bottom panels show variations on longer time scales. The offset of individual profiles is 0.25 of the continuum level.
