XTE J1118 480
XTE J1118+480 is a low-mass X-ray binary in the constellation Ursa Major. It is a soft X-ray transient that most likely contains a black hole and is probably a microquasar. Discovery XTE J1118+480 was discovered using the All-Sky Monitor on the Rossi X-Ray Timing Explorer satellite after it detected an outburst from the system on March 29, 2000. XTE is the standard designation for objects discovered by this satellite. It is also catalogued as 2MASS J11181079+4802126 in the Two-Micron All Sky Survey catalogue of infrared objects, and has been given the variable star designation KV Ursae Majoris. April–June outburst Much of what is known about XTE J1118+480 comes from data collected during the outburst in March 2000. The Rossi X-Ray Timing Explorer and the Advanced Research and Global Observation Satellite observed a quasi-periodic oscillation (QPO) from XTE J1118+480 as it evolved. The QPO is comparable to QPOs of other black-hole candidates. Properties The compact ...
