Astronomers detect X-ray emitting clumps ejected from the binary PSR B1259–63/LS 2883

Using NASA's Chandra X-ray observatory, astronomers have spotted X-ray-emitting clumps being ejected with high velocities from the gamma-ray binary PSR B1259–63/LS 2883. The findings were presented in a paper published March 2 on arXiv.org, in which the authors also discuss possible explanations of this phenomenon.
