The thermal structure and the location of the snow line in the protosolar nebula: axisymmetric models with full 3-D radiative transfer
M. Min, C. P. Dullemond, M. Kama +1
The precise location of the water ice condensation front ('snow line') in the protosolar nebula has been a debate for a long time. Its importance stems from the expected substantia…
The first stages of planet formation in binary systems: How far can dust coagulation proceed?
Andras Zsom, Zsolt Sandor, Cornelis Dullemond
We examine the first phase of the core accretion model, namely the dust growth/fragmentation in binary systems. In our model, a gas and dust disk is present around the primary star…
Dust size distributions in coagulation/fragmentation equilibrium: Numerical solutions and analytical fits
T. Birnstiel, C. W. Ormel, C. P. Dullemond
Context. Grains in circumstellar disks are believed to grow by mutual collisions and subsequent sticking due to surface forces. Results of many fields of research involving circums…
A new condition for the transition from runaway to oligarchic growth
C. W. Ormel, C. P. Dullemond, M. Spaans
Accretion among macroscopic bodies of ~km size or larger is enhanced significantly due to gravitational focusing. Two regimes can be distinguished. Initially, the system experience…
Gas- and dust evolution in protoplanetary disks
T. Birnstiel, C. P. Dullemond, F. Brauer
Context. Current models of the size- and radial evolution of dust in protoplanetary disks generally oversimplify either the radial evolution of the disk (by focussing at one single…
The outcome of protoplanetary dust growth: pebbles, boulders, or planetesimals? II. Introducing the bouncing barrier
A. Zsom, C. W. Ormel, C. Guettler +2
The sticking of micron sized dust particles due to surface forces in circumstellar disks is the first stage in the production of asteroids and planets. The key ingredients that dri…
