Frequencies of the most abundant types of realistic triples that become dynamically unstable during their evolution. The five main types are shown in the outer ring, and subtypes in the inner ring as indicated by the legend. The letters represent the stellar phases of the stars at the moment of the dynamical instability; MS for a main-sequence star, G for a giant, WD for a white dwarf. The first part of the name of the types represents the primary star, the second part the secondary. The name of the subtypes have a third part that represent the evolutionary state of the tertiary. The three pie charts reflect the three models for the initial population of triples on the zero-age main-sequence.
