We present the analysis of Chandra X-ray Observatory observations of the eccentric γ-ray binary PSR B1259–63/LS 2883. The analysis shows that the extended X-ray feature seen in previous observations is still moving away from the binary with an average projected velocity of ≈ 0.07 c ?> and shows a hint of acceleration. The spectrum of the feature appears to be hard (photon index Γ ≈ 0.8) with no sign of softening compared to previously measured values. We interpret it as a clump of plasma…
