| Abstract | We propose to observe the high-mass X-ray binary (HMXB) 1E 1145.1-6141simultaneously with XMM-Newton and NuSTAR for 40ks each. This will be the firstsensitive broad-band observations of this little studied source. The systemconsists of a neutron star and a B2 supergiant, which is one of the lateststellar types found in a HMXB. Our goal is to investigate the structure of theaccreted matter and the stellar wind and search for a cyclotron resonantscattering feature to constrain the magnetic field. We will describe thebroadband X-ray spectrum with state-of-the-art physical models to constrain thephysical conditions close to the neutron star and perform pulse phase-resolvedanalysis to constraint the emission geometry. |

| 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. |
