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 comma providing unprecedented observations of the disc.s evolution. We have recently observed PDS 70 in X-ray and UV with the textitkeyOpen SwiftkeyClose satellite and found that PDS 70 is in a short lived stage between the end of accretion and the final dispersal of the disc comma 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 comma which will enable accurate modelling of the disc dispersion and the consequences for planet formation.
