Extended Data Fig. 8: Variations in the radial emission of CO with angle.
From: Chemical tracers of a highly eccentric AGB–main-sequence star binary
The plots show the radial emission distribution against angle for the summed central three channels of CO (Fig. 5) with a full revolution shown in the centre (0 to 2π) and half a revolution is shown on either side ( − π to 0 and 2π to 3π) to show how the structures extend onwards. The location of the F9 star is indicated by the yellow star and a yellow dotted line which passes through both stars is plotted in the central winding to guide the eye. The black, red and white curves correspond to the same features highlighted in Fig. 5. The top plot shows the full observed extent of the CO emission (out to 15″) and the bottom plot focuses on the regions out to 5″ from the AGB star. These plots are reproduced without the additional curves in Supplementary Figure 4.
