Gravoturbulent planetesimal formation

Physica Scripta, 2008
We present a new scenario for the rapid formation of planetesimals based on the combined effects of turbulence and gravity. While it was generally accepted that these two effects cancel each other out, we found their interaction to be extremely beneficial for the accumulation of larger objects bound by gravity.

Xenon fractionation in porous planetesimals

Geochimica et Cosmochimica Acta, 1990
The distinctively fractionated Xe on Mars and Earth may have its root in a common source from which both planets accreted. We begin with Ozima and Nakazawa's hypothesis that terrestrial Xe fractionation was caused by gravitational separation of adsorbed solar nebular gases inside large porous planetesimals.

Planetesimal Population Synthesis: are Planetesimals formed in Pressure Bumps?

2019
Planetesimals, the smallest building blocks of planets that are gravitationally bound, are believed to be needed in order to form planets. The spacial distribution of these objects that are typically 100 km in diameter is important for the outcome of planet formation.
