Abstract | Optical follow-up observation have shown the RASS source RXJ~1442-0039 to be aneclipsing binary consisting of two stars of spectral type G5V+K1V. Modeling ofthe optical light curve shows the eclipse to be total, implying that largefractions of the stellar surfaces are occulted during optical primary andsecondary minimum. With its rather large X-ray flux RXJ~1442-0039 is thereforeextremely well suited to study the geometric location of the X-ray emission inactivestars. Detailed X-ray studies of RXJ~1442-0039 have never been carried outin the past, therefore we propose two XMM-Newton pointings centered on primaryandoptical secondary eclipse, respectively, to search for X-ray eclipses inRXJ~1442-0039. |

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. |
