Radially resolved simulations of collapsing pebble clouds in protoplanetary discs
Karl Wahlberg Jansson, Anders Johansen
We study the collapse of pebble clouds with a statistical model to find the internal structure of comet-sized planetesimals. Pebble-pebble collisions occur during the collapse and…
The role of pebble fragmentation in planetesimal formation II. Numerical simulations
Karl Wahlberg Jansson, Anders Johansen, Mohtashim Bukhari Syed +1
Some scenarios for planetesimal formation go through a phase of collapse of gravitationally bound clouds of mm-cm-sized pebbles. Such clouds can form for example through the stream…
The role of pebble fragmentation in planetesimal formation I. Experimental study
M. Bukhari Syed, J. Blum, K. Wahlberg Jansson +1
Previous work on protoplanetary dust growth shows halt at centimeter sizes owing to the occurrence of bouncing at velocities of 0.1 and fragmentation at velocities…
Formation of pebble-pile planetesimals
Karl Wahlberg Jansson, Anders Johansen
The first stage of planet formation is the accumulation of dust and ice grains into mm-cm-sized pebbles. These pebbles can clump together through the streaming instability and form…
