The central region of a planetary nebula is shown in a box. Labels indicate “Shock waves”, “Outflow collisions”, and an “Ionised jet” in the dust on both sides of the nebula. Close to the centre, “Dusty torus” and “Ionised torus” are marked. In the very middle, a faint dot inside a blotchy pink cloud is labelled “Dying star”. Bright stars surround the nebula and can be seen through the dust layers.

Two plots with three panels. Y-axis is normalised flix density, and x-axis on each is pulse phase. There are eight curves per panel, coloured individually and each representing a different frequency band. The left panel is the template and the remaining two panels are 50 days post event and 2 years post event. In the middle panel, three red arrows indicate regions of the profile that are affected by the change.

Two plots. In each the y-axis is the normalized flux density, whilst the x-axis is the pulse phase. There are two curves on the plot. The blue curve is the template and the orange curve is a single post event epoch. The orange curve is significantly deviated in shape relative to the blue curve.
