On Runaway Growth of Planetesimals
Icarus, 1996We present the results of three-dimensional N-body simulations of planetary accretion. We confirm that runaway growth is a dominant mode of planetary accretion in a three-dimensional system where orbits of planetesimals have inclinations. In runaway growth, larger planetesimals grow more rapidly than smaller ones and the mass ratio between them ...

The origin of the planetesimal theory
Origins of Life, 1977T. C. Chamberlin suggested in 1897, on the basis of geological and climatological arguments, that the planets were formed by accretion of cold solid partices. With F. R. Moulton he developed convincing arguments against the Laplace nebular hypothesis and published a comprehensive 'planetesimal theory' of the origin of the solar system in 1905.

The formation of Jupiter by hybrid pebble–planetesimal accretion
Nature Astronomy, 2018The standard model for giant planet formation is based on the accretion of solids by a growing planetary embryo, followed by rapid gas accretion once the planet exceeds a so-called critical mass1.

With a homogeneous sphere of icy silicate—a protoplanetary model suggested by Fowler, Greenstein, and Hoyle—the production and concentration of He3 resulting from bombardment by prehistoric solar protons are calculated as a function of time and sphere radius. The protons spallate isotopes of Li, Be, and B in a ‘skin’ about the sphere.
