Description Thermal emission from quiescent neutron stars is commonly used to constrain their internal structure. Although often neglected, low-level accretion in these systems may significantly affect the interpretation of this thermal emission. We recently began Swift monitoring of XTE J1701-462, to study low-level accretion and its impact on the quiescent properties. We detected episodes of enhanced activity, to at least 1e35 erg-s (up from 5e33 erg-s). Here, we request a 45 ks XMM ToO observation of XTE J1701-462 to study the source spectrum during a new flare episode, to better understand the nature of low-level accretion flows and estimate the amount of heating of the neutron star that takes place.

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.
