Title Is NeII a Tracer for X-Rays in Disks around Tauri Stars?

Description Although dust grains dominate the appearance of protoplanetary disks because of their high opacity, the key processes for disk evolution and planetesimal formation are driven through the dynamical state of the gas. In contrast to the dust component, we do not have a similar knowledge of the gas component. One of the Spitzer breakthroughs was the detection of the [Ne II] 12.8um line. Glassgold et al. (2007) proposed that this line provides diagnostics for a warm disk surface layer that is heated and ionized by stellar X-rays. A correlation of the [Ne II] luminosity with the X-ray luminosity is expected. The statistical sample so far available is insufficient to test this hypothesis. We aim at significantly enlarging the sample, with the goal of confirming or refuting this model.

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.
