Observation of aerodynamic instability in the flow of a particle stream in a dilute gas
Holly L. Capelo, Jan Molacek, Michiel Lambrechts +5
Forming macroscopic solid bodies in circumstellar discs requires local dust concentration levels significantly higher than the mean. Interactions of the dust particles with the gas…
How planetary growth outperforms migration
Anders Johansen, Shigeru Ida, Ramon Brasser
Planetary migration is a major challenge for planet formation theories. The speed of Type I migration is proportional to the mass of a protoplanet, while the final decade of growth…
Diffusion and Concentration of Solids in the Dead Zone of a Protoplanetary Disk
Chao-Chin Yang, Mordecai-Mark Mac Low, Anders Johansen
The streaming instability is a promising mechanism to drive the formation of planetesimals in protoplanetary disks. To trigger this process, it has been argued that sedimentation o…
Streaming Instability of Multiple Particle Species in Protoplanetary Disks
Noemi Schaffer, Chao-Chin Yang, Anders Johansen
The radial drift and diffusion of dust particles in protoplanetary disks affect both the opacity and temperature of such disks as well as the location and timing of planetesimal fo…
Slowing Down Type II Migration of Gas Giants to Match Observational Data
Shigeru Ida, Hidekazu Tanaka, Anders Johansen +2
The mass and semimajor axis distribution of gas giants in exoplanetary systems obtained by radial velocity surveys shows that super-jupiter-mass planets are piled up at > 1 au, whi…
Stellar abundance of binary stars: their role in determining the formation location of super-Earths and ice giants
Bertram Bitsch, Rebecca Forsberg, Fan Liu +1
Binary stars form from the same parent molecular cloud and thus have the same chemical composition. Forming planets take building material (solids) away from the surrounding protop…
