| Description | The recent discovery of a super-Earth transiting the bright star HD219134 provides an unprecedented opportunity for detailed study of the atmosphere of a low-mass exoplanet. The K3V star is located at a distance of only 6.5pc, enabling sensitive measurements of its X-ray flux and spectrum. This is important because X-ray/EUV irradiation is believed to drive the observed evaporation of hot Jupiters (HD209458b, HD189733b) and Neptunes (GJ436b), and HD219134b will extended these studies to the super-Earth regime. Here we propose an XMM-Newton observation that will define the high-energy environment of the planet and allow estimates of its atmospheric escape rate. This will aid the interpretation of atmosphere observations with HST, Spitzer, JWST etc. |

| 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. |
