Impact disruption of primordial planetesimals [PDF]

Planetary and Space Science, 2013
It isusually assumed that 1-10-km  sized planetesimals are formed    through coagulation processes and     continue to agglomerate via pairwise mergers.

Small planetesimals in a massive disk formed Mars

Icarus, 2013
Mars is likely to be a planetary embryo formed through collisions with planetesimals, which can explain its small mass and rapid formation timescale obtained from 182Hf-182W chronometry.

Thermal evolution of planetesimals during accretion

Icarus, 2017
cited By 2International audienceAlthough the mass distribution of planetesimals during the early stages of planetary formation has been discussed in various studies, this is not the case for their temperature distribution.

Radial Migration of Planetesimals

Astrophysics and Space Science, 1994
Planetesimals orbiting a protostar in a circumstellar disk are affected by gravitational interaction among themselves and by gas drag force due to disk gas. Within the Kyoto model of planetesimal accretion, the migration rate is interpreted as the inverse of the planetary formation time scale. Here, we study time scales of gravitational interaction and
