Core and crust formation on Vesta: Controlling factors
Abstract
We evaluate the differentiation history of Vesta as a function of the initial composition, density contrasts between the melt and the matrix, partitioning of 26Al, grain growth via Ostwald ripening, and the viscosity of the melt. To this end, we consider a partially molten planetesimal consisting of iron and silicates in the spherical symmetry, and compute the segregation of iron and silicate melt according to the flow in porous media theory by using the Darcy flow equation....
