Faster paleospin and deep-seated uncompensated mass as possible explanations for Ceres' present-day shape and gravity

X Mao, WB McKinnon - Icarus, 2018 - Elsevier
We show that Ceres' measured degree-2 zonal gravity, J 2, is smaller by about 10% than
that derived assuming Ceres' rotational flattening, as measured by Dawn, is hydrostatic …
