Extended Data Figure 1: Range of values for the degree-2 zonal gravity coefficient for Ceres.
From: A partially differentiated interior for (1) Ceres deduced from its gravity field and shape
We assume a two-layer model for Ceres and vary the density and radius of the core by solving Clairaut’s equations of rotational equilibrium at third order9. The best-fitting solution for J2 = 264.99 × 10−4 (blue line) is compared with the direct approach of Gao and Stevenson27 (red line), which generally shows a good agreement except at high core-density values. The white area at the upper right corresponds to solutions with shell density below 900 kg m−3.
