The physical properties of the stone meteorites provide important clues to understanding the
formation and physical evolution of material in the Solar protoplanetary disk as well …

This report summarizes observations of returned Apollo rocks and soils, lunar surface
images, orbital observations, and experimental impacts related to the erosion and …

We use a smooth particle hydrodynamics method to simulate colliding rocky and icy bodies
from centimeter scale to hundreds of kilometers in diameter in an effort to define self …

Impacts into solids are invariably accompanied by the abundant formation of cracks and
fragments created by crack linkage. In contrast to the dominantly compressive nature of …

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 …

We provide a unified discussion of the Yarkovsky effect in both the original,“diurnal” variant
and also for the “seasonal” variant which has been recently shown by Rubincam (1995) to …

AU Microscopii is a 12 Myr old M dwarf that harbors an optically thin, edge-on disk of dust.
The scattered light surface brightness falls with projected distance b from the star as b-α; …

Imaging of asteroids Gaspra and Ida and laboratory studies of asteroidal meteorites show
that impacts undoubtedly played an important role in the histories of asteroids and resulted …

We investigate the morphology of size–frequency distributions (SFDs) resulting from impacts
into 100-km-diameter parent asteroids, represented by a suite of 161 SPH/N-body …
