Numerical simulations of the accretion-ejection instability
Stuart Caunt, Michel Tagger
The Accretion-Ejection Instability (AEI) is explored numerically using a global 2d model of the inner region of a magnetised accretion disk. The disk is initially currentless but t…
The Accretion-Ejection Instability in X-ray Binaries
P. Varniere, M. Tagger
The Accretion-Ejection Instability (AEI), which can occur in magnetized disks near equipartition, is a good candidate to explain the low-frequency QPO in black-hole binaries. Here…
The Accretion Ejection Instability : Observationnal Tests
J. Rodriguez, P. Varniere, M. Tagger +1
The Accretion Ejection Instability (hereafter AEI), has been proposed to explain, the energy and angular momentum transport from the innermost parts of accretion disks in the X-Ray…
Ambipolar Filamentation of Turbulent Magnetic Fields : A numerical simulation
M. Franqueira, M. Tagger, A. I. Gomez de Castro
We present the results of a 2-D, two fluid (ions and neutrals) simulation of the ambipolar filamentation process, in which a magnetized, weakly ionized plasma is stirred by turbule…
