Disc dispersal in action\: XUV observations of the T-Tauri star PDS 70

PDS 70 recently became an object of immense interest following the discovery oftwo newly forming planets orbiting in a gap in the star.s protoplanetary disc.The system is close enough to be directly imaged, providing unprecedentedobservations of the disc.s evolution. We have recently observed PDS 70 in Xrayand UV with the \\textit{Swift} satellite and found that PDS 70 is in a shortlived stage between the end of accretion and the final dispersal of the disc,which is thought to be driven by stellar Xray and UV radiation. We propose 60ks of XMMNewton observations to obtain a far more detailed picture of thestar.s coronal emissions, which will enable accurate modelling of the discdispersion and the consequences for planet formation. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
