|Title||High Resolution Spectroscopy of 4U1626-67|
|Author||Dr Albert Brinkman|
|Description||GT- 4U1626-67 is a 7.7 pulsar with unusual properties. The binary has an extremely small mass function, which may imply that the mass donating star has extremely low mass, and may be just the burnt-out core of a more massive progenitor. This fact may be related to the unusually strong Ne Ly alpha emission feature seen in the ASCA spectrum, possibly a sign of anomalous abundances. A high resolution RGS spectrum will address the abundance issue, as well as clarify the puzzling physical conditions in the line emitting gas.|

|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.
