| Description | We propose a very deep (100 ks) XMM-Newton observation of the Fornax Dwarf Spheroidal galaxy. Our observational goal is to obtain X-ray colors or spectra for X-ray sources down to a luminosity limit of virgul3x10^33 erg/s. This limit is much deeper than has been obtained in any previous X-ray survey of low mass X-ray binary (LMXB) sources, and enables us to detect LMXBs in quiescence. Our primary science goal is to test models of LMXB formation and evolution by searching for sources that should have formed in past star formation episodes and testing StarTrack binary synthesis codes. The Fornax Dwarf Spheroidal is an excellent candidate for this study because its star formation history is relatively well determined and it is nearby. |

| 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. |
