Abstract Recently, a new class of type,I X-ray bursters was suggested, the burst-onlysources.., i.e. detected only during an X-ray burst, and no persistent emissionaround the burst. Short follow-up observations of several burst-only sourcescould not unambiguously identify the X-ray burster, but suggested that they wereat luminosities comparable to neutron star transients in quiescence. Thesesources are excellent candidates to study quiescent neutron stars, since theX-ray burst has unambiguously identified the compact object and they did notshow an outburst in recent times. This will allow us to test several theories onthe quiescent emission of neutron stars and open for the first time thepossibility to study X-ray bursters at the lowest accretion regime.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
