We present a determination of the mass, width and coupling of the strange resonances appear- ing in pion-kaon scattering below 1.8 GeV, namely the much debated K0∗(800) or κ, the scalar K0∗(1430), the K∗(892) and K∗(1410) vectors, the spin-two K2∗(1430) as well as the spin-three K3∗(1780). The parameters of each resonance are determined using a direct analytic continua- tion of the pion-kaon partial waves by means of Padé approximants, thus avoiding any particular model description of their pole positions and residues, while taking into account the analytic requirements imposed by dispersion relations.
