Abstract
Observing the famous high-mass, eccentric X-ray and γ-ray binary PSR B1259–63/LS 2883 with Chandra, we detected X-ray emitting clumps moving from the binary with speeds of ∼0.1c, possibly with acceleration. The clumps are being ejected at least once per binary period, 3.4 years, presumably around binary periastrons. The power-law spectra of the clumps can be interpreted as synchrotron emission of relativistic electrons. Here we report the results of 8 observations of the clumps in 2011–2017 (two binary cycles) and discuss possible interpretations of this unique phenomenon.
