Until now, the prismatic mass approximation of the topography and the constant density
assumption have been mostly utilized in topographic reductions, which are rough …

A gravitational field of an ore-bearing asteroid, which usually has an irregular shape and
heterogeneous density, is a prerequisite for asteroid exploration (eg, space mining) …

For polyhedral mass bodies having arbitrary shape and density distribution of polynomial
type we present a tensorial approach to derive analytical expressions of the gravitational …

The generally shaped polyhedron is a widely used model in gravity field modelling and
interpretation. Its induced gravity signal–gravitational potential and its derivatives up to …

We propose a new modified Parker's method for efficient gravitational forward modeling and
inversion using general polyhedral models. We have made several important modifications …

ABSTRACT A new high-order compact (HOC) cascadic multigrid (MG) strategy is developed
for modeling large-scale complex gravity problems on nonuniform rectilinear grids. First, the …

Gravity anomalies generated by density non-uniformity are governed by the 3D Poisson
equation. Most existing forward methods for such anomalies rely on integral techniques and …

The invariants of gravity (or gravitational) gradient tensor can be applied as the additional
internal parameters for the gravity gradient tensor, which have been widely used in the …

The traditional gravity forward modelling methods for solving partial differential equations
(PDEs) only can yield second-order accuracy. When computing the gravity field vector and …

ASTEROIDS and comets are often highly irregular in shape and can contain large density
inhomogeneities. For such bodies, the simple point-mass gravity model does not capture the …
