The Accretion-Ejection Instability has been proposed has been proposed to explain the low frequency Quasi-Periodic Oscillation (QPO) observed in low-mass X-Ray Binaries, in particular Black-Hole candidates. Its frequency, typically a fraction of the Keplerian frequency at the disk inner radius, is exactly in the range indicated by observations. We will show how this instability is able to produce a modulation of the X-ray flux and what are the characteristic of this modulation.
