We have calculated the figure of equilibrium of a rapidly rotating, differentiated body to determine the shape, structure, and composition of the dwarf planet Haumea. Previous studies of Haumea’s light curve have suggested Haumea is a uniform triaxial ellipsoid consistent with a Jacobi ellipsoid with axes ≈ 960 × 774 × 513 km, and bulk density ≈ 2600 kg m−3. In contrast, observations of a recent stellar occultation by Haumea indicate its axes are ≈ 1161 × 852 × 523 km and its bulk density… CONTINUE READING
