Title High energy irradiation and mass loss on the super earth GJ 1214b

Description We propose to observe the transiting super-earth system GJ 1214 for 25 ks with XMM-Newton. GJ 1214 is located 13 pc from Earth and shows the deepest visual-band transit of all close super-earths. The system is a suitable target for observations and, thus, a test-case for planetary and atmospheric modeling. The proposed observation will allow us to characterize the X-ray and UV emission of the host star, estimate the mass-loss rate and history of the planet, constrain models of GJ 1214b s atmosphere, and, finally, prepare the ground for more intensive follow-up studies.

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.
