|Title||From Super-Eddington to zero: following a Z source into quiescence|

|Description||XTE J1701-462 is probably the most luminous Galactic transient neutron star LMXB (NSXB) in the history of X-ray astronomy. Early observations have already clarified our view on the role of mass accretion rate in NSXBs. Observing XTE J1701-462 as it returns to quiescence will create a unique opportunity to study the effects of mass-accretion rate on the spectral-variability properties in a single NSXB over an unprecedented luminosity range. We propose a Chandra- XMM-Newton TOO program with two goals: 1) observe the source during the end of the decay and in quiescence, to complete what might well become a .Rosetta stone. for NSXBs and 2) constrain the structure of neutron stars by studying the effects of near-Eddington accretion on the cooling of the crust-core in transient NSXBs.|

|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.
