Caption: Figure 10.
Selected regions of the photospheric fit (red) to WD J0234-0406. In dotted red is the expected contribution of the circumstellar gas disk for the velocity profile that matches best the Ti features (see Section 3.2). The model photospheric + circumstellar gas spectrum without the fitted photospheric element is shown in blue. A red label is used for lines coming from the ground state.
