Planetesimal formation in an evolving protoplanetary disk with a dead zone
Astronomy & Astrophysics, 2019 Context. When and where planetesimals form in a protoplanetary disk are highly debated questions. Streaming instability is considered the most promising mechanism, but the conditions for its onset are stringent.

The Multifaceted Planetesimal Formation Process [PDF]
, 2014 Accumulation of dust and ice particles into planetesimals is an important step in the planet formation process. Planetesimals are the seeds of both terrestrial planets and the solid cores of gas and ice giants forming by core accretion. Left-over planetesimals in the form of asteroids, trans-Neptunian objects and comets provide a unique record of the ...

Numerical modeling of gravitational instability outcomes in multiphase circumstellar discs
EPJ Web of Conferences, 2013 To suggest consistent route toward planetesimal and planetary core formation in circumstellar discs we study gravitational instability outcomes in massive multiphase (gas-collisionless bodies) disc.

, 2007 We show that interaction with a gas disk may produce young planetary systems with closely-spaced orbits, stabilized by mean-motion resonances between neighbors.

Planetesimal Drift in Eccentric Disks: Possible Outward Migration
The Astrophysical JournalRadial drift of solid particles in the protoplanetary disk is often invoked as a threat to planet formation, as it removes solid material from the disk before it can be assembled into planets.

Formation Of Planetesimals And Planets
, 2018 In this Bridge Talk, we intend to summarize our current understanding of planetesimal and planet formation. For planetesimal formation, we will emphasize recent theoretical and laboratory work on the evolution of dust in protoplanetary disks. We will discuss possible pathways towards planetesimals and their consequences on planetesimal properties ...

Planetesimal Scattering Efficiency of Cold Giant Planet Architectures
The Astronomical JournalThe discovery of many exoplanets has revealed an incredible diversity of orbital architectures. These orbital configurations are intrinsically linked to the potential for habitable environments within the system, since the gravitational influence of the ...
