Fast accretion of small planetesimals by protoplanetary cores
Roman R. Rafikov
We explore the dynamics of small planetesimals coexisting with massive protoplanetary cores in a gaseous nebula. Gas drag strongly affects the motion of small bodies leading to the…

Effects of Planetesimal Dynamics on the Formation of Terrestrial Planets
Roman R. Rafikov
Formation of terrestrial planets by agglomeration of planetesimals in protoplanetary disks sensitively depends on the velocity evolution of planetesimals. We describe a novel semi-…

Dynamical evolution of planetesimals in protoplanetary disks
Roman R. Rafikov
The current picture of terrestrial planet formation relies heavily on our understanding of the dynamical evolution of planetesimals -- asteroid-like bodies thought to be planetary…
