Planet formation: The case for large efforts on the computational side
Wladimir Lyra, Thomas Haworth, Bertram Bitsch +54
Modern astronomy has finally been able to observe protoplanetary disks in reasonable resolution and detail, unveiling the processes happening during planet formation. These observe…
Planetesimal formation in self-gravitating discs -- dust trapping by vortices
P. G. Gibbons, G. R. Mamatsashvili, W. K. M. Rice
The mechanism through which meter-sized boulders grow to km-sized planetesimals in protoplanetary discs is a subject of active research, since it is critical for planet formation.…
Planetesimal formation in self-gravitating discs: the effects of particle self-gravity and back-reaction
P. G. Gibbons, G. R. Mamatsashvili, W. K. M. Rice
We study particle dynamics in self-gravitating gaseous discs with a simple cooling law prescription via two-dimensional simulations in the shearing sheet approximation. It is well…
Revisiting linear dynamics of non-axisymmetric perturbations in weakly magnetized accretion discs
G. R. Mamatsashvili, G. D. Chagelishvili, G. Bodo +1
We investigate linear dynamics of non-axisymmetric perturbations in incompressible, vertically stratified Keplerian discs with a weak vertical magnetic field in the shearing box ap…
Planetesimal Formation In Self-Gravitating Discs
P. G. Gibbons, W. K. M. Rice, G. R. Mamatsashvili
We study particle dynamics in local two-dimensional simulations of self-gravitating accretion discs with a simple cooling law. It is well known that the structure which arises in t…
Axisymmetric modes in vertically stratified self-gravitating discs
G. R. Mamatsashvili, W. K. M. Rice
We perform linear analysis of axisymmetric vertical normal modes in stratified compressible self-gravitating polytropic discs in the shearing box approximation. We study specific d…
Vortices in self-gravitating gaseous discs
G. R. Mamatsashvili, W. K. M. Rice
(abridged) Vortices are believed to play a role in the formation of km-sized planetesimals. However, vortex dynamics is commonly studied in non-self-gravitating discs. The main goa…
