Gravito-turbulence and dynamo in poorly ionised protostellar discs. I. Zero-net-flux case
A. Riols, W. Xu, G. Lesur +2
In their early stages, protoplanetary discs are sufficiently massive to undergo gravitational instability (GI). This instability is thought to be involved in mass accretion, planet…
Ring formation and dust dynamics in wind-driven protoplanetary discs: global simulations
A. Riols, G. Lesur, F. Menard
Large-scale vertical magnetic fields are believed to play a key role in the evolution of protoplanetary discs. Associated with non-ideal effects, such as ambipolar diffusion, they…
Dust dynamics and vertical settling in gravitoturbulent protoplanetary discs
A. Riols, B. Roux, H. Latter +1
Gravitational instability (GI) controls the dynamics of young massive protoplanetary discs. Apart from facilitating gas accretion on to the central protostar, it must also impact o…
Spontaneous ring formation in wind-emitting accretion discs
A. Riols, G. Lesur
Rings and gaps have been observed in a wide range of protoplanetary discs, from young systems like HLTau to older discs like TW Hydra. Recent disc simulations have shown that magne…
Dust settling and rings in the outer regions of protoplanetary discs subject to ambipolar diffusion
A. Riols, G. Lesur
MHD turbulence plays a crucial role in the dust dynamics of protoplanetary discs. It affects planet formation, vertical settling and is one possible origin of the large scale axisy…
Spiral density waves and vertical circulation in protoplanetary discs
A. Riols, H. Latter
Spiral density waves dominate several facets of accretion disc dynamics --- planet-disc interactions and gravitational instability (GI) most prominently. Though they have been exam…
Gravito-turbulence and the excitation of small-scale parametric instability in astrophysical discs
A. Riols, H. Latter, S-J. Paardekooper
Young protoplanetary discs and the outer radii of active galactic nucleii may be subject to gravitational instability and, as a consequence, fall into a `gravitoturbulent' state. W…
