High accretion rates in magnetised Keplerian discs mediated by a Parker instability driven dynamo
Anders Johansen, Yuri Levin
Hydromagnetic stresses in accretion discs have been the subject of intense theoretical research over the past one and a half decades. Most of the disc simulations have assumed a sm…

Embryos grown in the dead zone: Assembling the first protoplanetary cores in low mass self-gravitating circumstellar disks of gas and solids
W. Lyra, A. Johansen, H. Klahr +1
In the borders of the dead zones of protoplanetary disks, the inflow of gas produces a local density maximum that triggers the Rossby wave instability. The vortices that form are e…

A coagulation-fragmentation model for the turbulent growth and destruction of preplanetesimals
Anders Johansen, Frithjof Brauer, Cornelis Dullemond +2
To treat the problem of growing protoplanetary disc solids across the meter barrier, we consider a very simplified two-component coagulation-fragmentation model that consists of ma…
