All the contemporary XMM-Newton, NuSTAR and Suzaku observations from 2001-2014 were revisited and we find that the centroid energy of the blueshifted Fe K absorption profile increases with luminosity. This translates into a correlation between the wind outflow velocity and the hard X-ray luminosity (between 7 and 30 keV) where we find that v_w/c∝ L_{7-30}^{γ } where γ = 0.22 ± 0.04. We also show that this is consistent with a wind that is predominately radiatively driven, possibly resulting from the high Eddington ratio of PDS 456.STAMPAenEvidence for a radiatively driven disc-wind in PDS 456?Article10.1093/mnrasl/slx1292-s2.0-85041905347000438218200004https://academic.oup.com/mnrasl/article-abstract/472/1/L15/40828372017MNRAS.472L..15MFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_6 Stars and stellar systems
