Description Understanding what happens to rocky planets and their atmospheres in the habitable zones of low mass stars is currently one of the greatest astronomical challenges. As part of our HST MUSCLES project, we shall collect XMM-Newton EPIC observations of two of the nearest low-mass exoplanet hosts with Super-Earths orbiting in-near their habitable zones (the K dwarfs - HD40307, HD85512). We will measure their X-ray luminosities and coronal temperatures, and derive the high energy radiation field to facilitate exoplanet atmospheric modeling. These planetary systems allow study of exoplanet atmospheric chemistry and evolution under a diversity of physical situations. X-ray heating enhances evaporation and atmospheric escape, which impacts long-term stability of exoplanet atmospheres.

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.
