Abstract | We propose XMM-Newton observations of new candidate supersoft X-ray sources,SSSs, in the Magellanic Clouds, MCs, in order to confirm and study their nature.The 20 ks exposures will allow to determine a precise position, spectral andtemporal investigations. Finding new SSS in the MCs is crucial for X-ray sourcepopulation studies and will provide new information on the physics of individualobjects and on the class of SSSs as such. In particular we will address thequestion if persistent low-luminosity SSSs exist, which is not easily tounderstand in the framework of stable burning at high accretion rates, or ifthey are highly variable. |

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. |
