XTE J1906+090 is a persistent low-luminosity Be X-ray binary, study suggests

Using INTEGRAL and Swift spacecraft, European astronomers have observed an unidentified X-ray source known as XTE J1906+090. Results of the observational campaign, presented May 11 on the arXiv preprint server, suggest that this source belongs to the small and rare group of persistent low-luminosity Be X-ray binaries.
