Title Spectroscopy of a Neutron Star Transient in Outburst

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

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.
