How the chemical composition of solids influences the formation of planetesimals

The formation of planetesimals is a necessary step for the formation of planets. While several methods exist that can explain the formation of planetesimals, an increase in the local dust-to-gas ratio above unity is a strong requirement to trigger the ...

Considering Contact Forces during the Formation of Planetesimals by Gravitational Collapse: Mutual Orbits, Spin States, and Shapes

The Astrophysical Journal
In this work, we apply a soft-sphere discrete element method (SSDEM) within the PKDGRAV N -body integrator to investigate the formation of planetesimal systems through the gravitational collapse of clouds of superparticles. Previously published numerical

Growth of Planetesimals and the Formation of Debris Disks [PDF]

, 2012
At the edge of the Solar System lies the Kuiper Belt, a ring of leftover planetesimals from the era of planet formation. Collisions between the Kuiper Belt Objects produce dust grains, which absorb and re-radiate stellar radiation.
