		| Abstract: | X-ray variability in Wolf-Rayet binary systems is related to orbital eccentricity, eclipses
 and the density-dependent plasma physics of collisionless shocks. Intensive
 campaigns on WR 25, WR 140 and other stars have shown what a rich variety of
 physics can be investigated through well-designed observations. |
