| Description | We propose three 60 ksec and one 140 ks XMM-Newton observations of the dipping Low-Mass X-ray Binaries (LMXBs) XB 1254-690 and 4U 1746-371. We will obtain up to virgul12 ks of dip data per 4U 1254-690 observation which will be sufficient to reliably measure the dip properties and the changes in the absorber, compared to the persistent emission. The 140 ks of the 4U 1746-12 observation, added to a previous 50 ks XMM-Newton observation on this source, will be enough to detect with high significance the Fe XXVI absorption feature seen in the previous observation at low confidence in the persistent emission and Fe XXV and/or Fe XXVI absorption features in the dipping emission. The significant detection of these lines will allow the absorber properties to be unambigously characterized. |

| 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. |
