Black hole X-ray binary GRS 1915+105 has a variable magnetic disc wind, study suggests

Using NASA's Chandra spacecraft, astronomers have performed high-resolution X-ray spectroscopic observations of a transient black hole X-ray binary known as GRS 1915+105. They report that the source exhibits a variable magnetic accretion disc wind. The study was detailed in a paper published December 16 on the arXiv pre-print repository.
