X-ray bursters are one class of X-ray binary stars exhibiting periodic and rapid increases in luminosity ( typically a factor of 10 or greater ) peaked in the X-ray regime of the electromagnetic spectrum.

X-ray bursters differ observationally from other X-ray transient sources ( such as X-ray pulsars and soft X-ray transients ), showing a sharp rise time ( 1 – 10 seconds ) followed by spectral softening ( a property of cooling black bodies ).

Most X-ray bursters have irregular periods, which can be on the order of a few hours to many months, depending on factors such as the masses of the stars, the distance between the two stars, the rate of accretion, and the exact composition of the accreted material.

Soft X-ray transients Cen X-4 and Aql X-1 were discovered by Hakucho, Japan's first X-ray astronomy satellite to be X-ray bursters.
