Modulation of the X-ray Fluxes by the AEI
P. Varnière, M. Muno, M. Tagger +1
The Accretion-Ejection Instability (AEI) has been proposed to explain the low frequency Quasi-Periodic Oscillation (QPO) observed in low-mass X-Ray Binaries. Its frequency, typical…
Low-frequency QPO, Magnetic Flood and the states of GRS 1915+105
M. Tagger
We sum up progress accomplished, since the last microquasar workshop, on the physics of the Accretion-Ejection Instability (AEI), and its ability to explain the properties of the l…
RXTE Observations of the Microquasar GRS 1915+105
J. Rodriguez, P. Durouchoux, M. Tagger
We analyse a set of three RXTE Target of Opportunity observations of the Galactic microquasar GRS 1915+105, observed in April 2000. We concentrate on the timing properties of the s…
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…
