Abstract
We report STAR results on the azimuthal anisotropy parameter for strange particles , , and at midrapidity in collisions at at the Relativistic Heavy Ion Collider. The value of as a function of transverse momentum, , of the produced particle and collision centrality is presented for both particles up to . A strong dependence in is observed up to . The measurement is compared with hydrodynamic model calculations. The physics implications of the integrated magnitude as a function of particle mass are also discussed.
