Growth of individual components in the triple diagnostic diagram. Assume a triple system has evolved to reach the mass ratios A:B:C = 2:1:3 (e.g., M_A = 0.04, M_B = 0.02, M_C = 0.06 M_⊙), which corresponds to the location at the center of the diagram, and then assume each component is doubled in mass while the other two are kept constant. The three arrows show the new locations in the diagram.
