An Accretion-Ejection Instability in magnetized disks
M. Tagger, R. Pellat
We present an instability occurring in the inner part of disks threaded by a moderately strong vertical (poloidal) magnetic field. Its mechanism is such that a spiral density wave…

The Parker instability in disks with differential rotation
T. Foglizzo, M. Tagger
We present a detailed study of the growth of the Parker instability in a differentially rotating disk embedded in an azimuthal equilibrium magnetic field, such as the interstellar…
