A strong surge of emission from an X-ray binary. Bursts are of short duration, typically less than 1 min. So-called type I bursts are a result of thermonuclear fusion of material accreted on to the surface of a neutron star. Type II bursts are only found in one object, the Rapid Burster (MXB 1730–335), and are caused by spasmodic accretion.
