| Abstract | We propose XMM-Newton/EPIC observations of 14 recently discovered nearbyexoplanet hosts. Together, they host a combined 7 earth-like planets and 36known planets overall. Many of the planets are located in or near the presumedhabitable zones of their host stars. The targets cover stellar types from F toM. While a stars photometric luminosity is important, the high energy UV/X-rayirradiation from the corona is a major driver of photochemistry, upperatmospheric heating, and atmospheric mass loss in exoplanets. We will obtain asnapshot of the current temperatures and fluxes using EPIC-PN/MOS. These datawill start the process of understanding the possible paths of atmosphericevolution. |

| 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. |
