Fig. 12
Left: absorption lines of the neutral metals with emission cores. The left arrow at 4045.81 Å marks the self-absorption in the core of the strong Fe I absorption line. In the S spectrum the strong emission detail in the core of the nearby Dy I λ 4045.97 Å line is marked by the right arrow. In the QC spectrum the detail is “eaten” by self-absorption. Self-absorption in the weak emission core of K I line at λ 4047.21 is seen as well. Right: example of iP Cyg profiles.
