Movie S1
Mpeg movie showing the simulation of the mass ejection during the merger phase. Left panel: particle plot showing particles that are ejected in red and particles that remain bound in blue. The scale is in units of 1500 R. Right panel: Histogram of the mass (left axis) ejected as a function of sin θ, where θ is the angle with respect to the equatorial plane. The thin blue curves give the median velocity (central curve) and the range of velocities (upper and lower curves) that includes 50% of the ejecta at a given sin θ. The velocities are given on the right axis.

Movie S2
Mpeg movie showing the formation of the triple-ring nebula as a result of the interaction of the blue-supergiant wind (gray particles) with the matter ejected in the merger phase (green/blue particles). The color of the ejecta particles indicates the logarithm of the mass density in units of g cm^-3 (see scale bar). The spatial scale is in units of pc.
