TL;DR: Analysis of data from the Dawn spacecraft implies that asteroid Vesta is rich in volatiles, and models of Vesta’s evolution based on studies of howardite, eucrite, and diogenite meteorites are tested, finding that global Fe/O and Fe/Si ratios are consistent with HED compositions.

TL;DR: In this paper, the potential geochemical and geophysical diversity of a fully differentiated Vesta-sized parent body with a eucrite crust (e.g., core size and density, crustal thickness).

TL;DR: The Gamma Ray and Neutron Detector (GRaND) on board the NASA Dawn spacecraft provided constraints on the abundance and distribution of Fe, Ca, Al, Mg, and other rock-forming elements as discussed by the authors.

TL;DR: In this paper, a mapping study of 7.6 MeV gamma rays produced by neutron capture by Fe at the surface of the main belt asteroid 4 Vesta as measured by the bismuth germanate scintillator of the Gamma Ray and Neutron Detector (GRaND) on the Dawn spacecraft is presented, along with a global map.

TL;DR: In this article, the authors investigated the interplay between translation and convection in a 3D spherical model with permeable boundary conditions, and showed that translation is almost completely hampered by convective motions for viscosities lower than 10 17 Pa s and the phase change becomes an almost impermeable boundary.
