Description | We propose to observe the star CN Leo (spectral type M6Ve) simultaneously with XMM-Newton in the X-ray and optical band (with its optical monitor) and with UVES on Kueyen to obtain time-resolved high-resolution spectroscopy. CN Leo does show frequent flares in the X-ray and optical band, hence we expect a number of such events during the proposed observations. With theobservational setup the photospheric, chromospheric and coronal energy losses of both the quiescent and flaring emission of CN Leo can be simultaneously recorded. The UVES observations will cover the Fe XIII 3388.1 A line, which also traces the coronal emission from CN Leo from the ground. With its superb spectral resolu tion (R virgul 45000) we can study in detail the coronal and chromospheric dynamics. |

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. |
