It had previously been claimed that XTE J1739−285 was the fastest-spinning celestial body yet known, with a frequency of 1122 Hz.[3] However, a re-analysis of these data by other astronomers has been unable to reproduce this result.[4]
XTE J1739−285 has been proposed as a possible quark star, as well as 3C 58.
