Formation of pebbles in (gravito-)viscous protoplanetary disks with various turbulent strengths
Eduard I. Vorobyov, Vardan G. Elbakyan, Anders Johansen +3
Aims. Dust plays a crucial role in the evolution of protoplanetary disks. We study the dynamics and growth of initially sub- dust particles in self-gravitating young protoplane…
Mean motion resonance capture in the context of type-I migration
Kaltrina Kajtazi, Antoine C. Petit, Anders Johansen
Capture into mean motion resonance (MMR) is an important dynamical mechanism as it shapes the final architecture of a planetary system. We simulate systems of two or three planets…
The coexistence of the streaming instability and the vertical shear instability in protoplanetary disks: Planetesimal formation thresholds explored in two-dimensional global models
Urs Schäfer, Anders Johansen
The streaming instability is a promising mechanism to induce the formation of planetesimals. Nonetheless, this process has been found in previous studies to require either a dust-t…
Growing the seeds of pebble accretion through planetesimal accretion
Sebastian Lorek, Anders Johansen
We explore the growth of planetary embryos by planetesimal accretion up to and beyond the point where pebble accretion becomes efficient at the so-called Hill-transition mass. Both…
Anatomy of rocky planets formed by rapid pebble accretion II. Differentiation by accretion energy and thermal blanketing
Anders Johansen, Thomas Ronnet, Martin Schiller +2
We explore the heating and differentiation of rocky planets that grow by rapid pebble accretion. Our terrestrial planets grow outside of the ice line and initially accrete 28\% wat…
Anatomy of rocky planets formed by rapid pebble accretion I. How icy pebbles determine the core fraction and FeO contents
Anders Johansen, Thomas Ronnet, Martin Schiller +2
We present a series of papers dedicated to modelling the accretion and differentiation of rocky planets that form by pebble accretion within the lifetime of the protoplanetary disc…
