Fig. 12
Upper panels: location of the chromospheric spot and the local spectra corresponding to the undisturbed photosphere (absorption) and to the spot (emission). Lower panels: left – profiles of the Ca i λ 6039 Å line, corresponding to phases 0.0 (spot facing the observer, solid line), 0.22 and 0.78 (maximal blue- and red-shifted absorption, dotted lines). Dashed profile: a normal photosphere without spot; right – RV-variations of absorption lines (open circles) and emission lines (filled circle).
