Description XTE J1814-338 is the 5th transient millisecond X-ray pulsar (TMXP) discovered. In outburst and in quiescence TMXP are peculiar, showing faint outbursts, weaker quiescent luminosities and (when detected) lack of the soft component usually observed in other quiescent transients. Here we propose to observe for the first time XTE J1814-338 in quiescence. In the last few years a good sample of quiescent transients have been observed providing spectral information with some details and allowing to study the sample of quiescent transients statistically. Only one source has too few counts (22) to asses its quiescent spectrum: XTE J2123-058. Here we ask to observe this source to complement existing data and to disentangle the soft and hard components in its spectrum.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
