| Swift J1749 pulsar and companion star, illustration. The X-ray pulsar at left was discovered as it was eclipsed by its companions star (right), a K-type star. It was discovered using NASA's Rossi X-ray Timing Explorer (RXTE). The system erupted with an X-ray outburst on 10 April 2010. During the event, RXTE observed three eclipses, detected X-ray pulses that identified the neutron star as a pulsar, and recorded pulse variations that indicated the neutron star's orbital motion. The system is located 22, 000 light years away in the constellation Sagittarius. Illustration published in 2010. | |
