The howardite, eucrite and diogenite (HED) clan of meteorites are ultramafic and mafic
igneous rocks and impact-engendered fragmental debris derived from a thoroughly …

Collisions are one of the key processes sha** planetary systems. Asteroid families are
outcomes of such collision still identifiable across our solar system. The families provide a …

Context. Until recently, the 3D shape, and therefore density (when combining the volume
estimate with available mass estimates), and surface topography of the vast majority of the …

The Dawn spacecraft targeted 4 Vesta, believed to be a remnant intact protoplanet from the
earliest epoch of solar system formation, based on analyses of howardite-eucrite-diogenite …

Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally
stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large …

The number of asteroids with accurately determined orbits increases fast, and this increase
is also accelerating. The catalogs of asteroid physical observations have also increased …

The mineralogy of Vesta, based on data obtained by the Dawn spacecraft's visible and
infrared spectrometer, is consistent with howardite-eucrite-diogenite meteorites. There are …

A new family classification, based on a catalog of proper elements with∼ 384,000
numbered asteroids and on new methods is available. For the 45 dynamical families with> …

INTRODUCTION Thermochemical models have predicted that the dwarf planet Ceres has,
to some extent, formed a mantle. Moreover, due to viscous relaxation, these models indicate …

The Dawn mission has provided new evidence strengthening the identification of asteroid
Vesta as the parent body of the howardite, eucrite, and diogenite (HED) meteorites. The …
