Neutron Star KS
1731-260
A Chandra image of neutron star KS 1731-260, remarkably cool after 12 years of being bombarded with hot gas from a companion star, not visible here. The now dim KS 1731-260 is the light blue object slightly above the midline of this image.

X-ray Light Curve for KS
1731-260
Data from two detectors aboard the Rossi X-ray Timing Explorer (RXTE) shows the light curve (X-ray count rate versus time) for the neutron star KS 1731-260. The day the Chandra observation was performed is marked with an arrow.
