Abstract | A recent observation of Serpens X-1 with NuSTAR has clearly revealed arelativistic Fe K line (confirming prior XMM-Newton results), as well as theCompton reflection hump. We propose to build on this by making two 40 ksXMM-Newton + NuSTAR observations of a transient neutron star LMXB in outburst.Leveraging their complementary strengths, this program will aim to constrain thestellar radius, search for disk winds like those seen in black holes (and asmall but growing number of neutron stars), and to understand the evolution ofneutron star accretion flows over a broader range of accretion rates than can beobserved in persistent Z.. and atoll.. sources. |

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. |
