Description In order to further our understanding of the emitting and absorbing material in
high-mass X-ray binaries (HMXB) and the accretion states of the sources,we
propose a total of 30 ksec XMM-Newton observation of 4U 1907+09 to be conducted
as two 15 ksec observations at different binary phases.In two archival ASCA SIS
spectra of 4U 1907+09,we found evidence for the presence of 6.9 keV Fe XXVI
absorption features at around 2sigma confidence which will yield 5sigma
detection with EPIC pn CCDs and the modelling will allow the properties of a
photo-ionized absorber to be determined for the first time in a HMXB. Our
proposed observation at the chosen phases will for the first time determine
spectra at low count rate levels over a factor of 100 difference from the source.

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.
