The anisotropy parameter v2 carries information about the early stage of high-energy nucleus-nucleus collisions. Due to the presumably small cross-section of strange hadrons with the wealth of non-strange particles in the hadronic phase, the already observed strong flow of strange hadrons must be developed during a partonic phase of the hot and dense system. The comparison of v2 for baryons with different strangeness content will allow the disentanglement of the contributions of the u, d, and s-quarks to the overall flow of strange baryons.
We will present results on v2(pT) for the multi-strange baryons Xi and Omega, obtained from high-statistics measurements at sqrt(s_NN) = 200 GeV with the STAR detector. The detailed studies of azimuthal anisotropy up to pT = 5-6 GeV/c will focus on measurements of the centrality dependence and comparisons with other particle species and model expectations.
