J.-L. Touraine,M. C. Favrot,M. El Ansarysystems may contain solid circumstellar matter. Observed velocities are usually several hundred km s .. The empirical relation between the velocity of rotation of disks and the orbital period is described. Finally, the stability of these features is briefly discussed.
