We propose XMM-Newton-EPIC observations of 14 recently discovered nearby exoplanet hosts. Together comma 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 comma the high energy UV-X-ray irradiation from the corona is a major driver of photochemistry comma upper atmospheric heating comma 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.
