Scaled spin rate versus specific angular momentum: scaled spin rate and specific angular momenta computed as mentioned in the text. We indicate the MacLaurin and the Jacobi sequences. The “high size ratio binaries”, as indicated in Descamps & Marchis (2008), are located near the MacLaurin/Jacobi transition. The legend is as follows: the black triangle denotes Salacia-Actaea, the gray diamond Haumea-Namaka, the black diamond Haumea-Hi’iaka, the gray triangle Varda-Ilmarë, the gray square Quaoar-Weywot, the black circle Orcus-Vanth assuming a secondary-to-primary mass ratio of 0.03, the gray circle Orcus-Vanth assuming a secondary-to-primary mass ratio of 0.09, and black square for Typhon-Echidna. The system 2007 TY₄₃₀ is not plotted here because we restricted the plot for a better visualization). Error bars are approximate.
