| 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. |
