Fig. 13.
Left panel: SiO emission distribution in the 1.4 km s−1 channel, zoomed in on the central 2″ × 2″. The local void is clearly visible. The purple and white dashed circles have been added to guide the eye, centred on the continuum brightness peak location and the local void, respectively. Right panel: CO emission in the same channel. A lane of gas is seen bridging the gap between the AGB star and the position of the local void.
