|Title||X-rays in the prime of life: High Energy Dose to Exo-Earths|
|Author||Dr Scott Wolk|
|Description||We propose XMM-Newton-EPIC observations of 14 recently discovered nearby exoplanet hosts. Together, they host a combined 7 earth-like planets and 36 known planets overall. Many of the planets are located in or near the presumed habitable zones of their host stars. The targets cover stellar types from F to M. While a star.s photometric luminosity is important, the high energy UV-X-ray irradiation from the corona is a major driver of photochemistry, upper atmospheric heating, and atmospheric mass loss in exoplanets. We will obtain a snapshot of the current temperatures and fluxes using EPIC-PN-MOS. These data will start the process of understanding the possible paths of atmospheric evolution.|

|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.
