| Abstract | We propose XMM-Newton observations of 8 regions of the LMC with the strongestclean star-formation episodes in the ~6-50 Myr age range. These observationswill probe the X-ray source populations in regions of different stellar content,down to a luminosity of ~10^33 erg/s in our nearest star-forming galaxy. Fromtheir optical counterparts we will classify the X-ray sources as supergiants orBe/X-ray binaries (SG- or Be-XRBs), while based on X-ray spectra and timinganalysis we will identify X-ray binary pulsars. These results will address theconnection between stellar and different XRB sub-populations. The proposedobservations will complement previous X-ray studies of the LMC as well asinvestigations in other galaxies where these faint XRB populations cannot be observed. |

| 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. |
