Description PDS 70 recently became an object of immense interest following the discovery of two newly forming planets orbiting in a gap in the star.s protoplanetary disc. The system is close enough to be directly imaged, providing unprecedented observations of the disc.s evolution. We have recently observed PDS 70 in X-ray and UV with the textit{Swift} satellite and found that PDS 70 is in a short lived stage between the end of accretion and the final dispersal of the disc, which is thought to be driven by stellar X-ray and UV radiation. We propose 60 ks of XMM-Newton observations to obtain a far more detailed picture of the star.s coronal emissions, which will enable accurate modelling of the disc dispersion and the consequences for planet formation.

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.
