Pseudo-ring structure in the final remnant of model M9PsRb, made of stars that initially belonged to the primary disc (experiment h in Table 3). It coincides with the location of the two twin symmetric clumps observed in the stellar satellite material in the final remnant. Both substructures are associated with an oval distortion induced by the satellite accretion (see Fig. 5). The pseudo-ring has been marked with a white dashed circle. A rainbow colour palette is used to represent different surface density levels on a logarithmic scale, with redder colours indicating higher values. All physical quantities are given in simulation units.
