Abstract | Understanding what happens to rocky planets and their atmospheres in thehabitable zones of low mass stars is currently one of the greatest astronomicalchallenges. As part of our HST MUSCLES project, we shall collect XMM-Newton EPICobservations of two of the nearest low-mass exoplanet hosts with Super-Earthsorbiting in/near their habitable zones (the K dwarfs - HD40307, HD85512). Wewill measure their X-ray luminosities and coronal temperatures, and derive thehigh energy radiation field to facilitate exoplanet atmospheric modeling. Theseplanetary systems allow study of exoplanet atmospheric chemistry and evolutionunder a diversity of physical situations. X-ray heating enhances evaporation andatmospheric escape, which impacts long-term stability of exoplanet atmospheres. |

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. |
