| Description | In 2009 and 2011 we observed HD 189733 with XMM-Newton at the eclipse of its hot Jupiter. We found a striking similarity in a relatively bright flare just after the end of the planet eclipse in both observations. The corona of this virgul5Gyr old star is extraordinarily unusual: it is cold, dense, and flaring very frequently. We propose to observe HD 189733 at the planet eclipse, as in 2009 and 2011, to test if the planet is triggering flare activity on the stellar corona when at a well precise phase. With the RGS spectra we will assess any changes in the line intensity of He-like triplets and Fe on a time scale of one to three years. |

| 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. |
