X-ray burster Source with intense flashes, or bursts, of X-rays. The bursts have rise times of around 1 second and can last as little as 10 seconds, yet the energy released is equivalent to a week's output from the Sun (or more). A few X-ray bursts have been detected at optical wavelengths. X-ray bursters are BINARY STAR systems in which one star is a NEUTRON STAR. The neutron star is surrounded by a hydrogen-rich ACCRETION DISK from a low-mass companion star (around one solar mass). The hydrogen flows from the accretion disk on to the surface of the neutron star and is burnt to helium (see NUCLEAR REACTIONS). When the amount of helium on the surface of the neutron star exceeds a critical amount, the helium suddenly ignites, causing a burst of X-rays. The temperature can rise to 30 million K at the peak of the burst and 10 seconds later fall back to15 million K. Almost 30 X-ray bursters have been found in GLOBULAR CLUSTERS; for example, the first was found in NGC 6624 (Omega Centauri has five, M22 has four). They are generally found close to the centre of the cluster, where the star density is very high. These X-ray bursters are also thought to be binary stars, with a neutron star accreting material from a low-mass companion star.
