    "abstract": "Based on the phase-space information obtained from a multi-phase transport\nmodel within the string melting scenario for strange and antistrange quarks, we\nstudy the yields and transverse momentum spectra of $\\phi $ mesons and $\\Omega\n$ ($\\Omega ^{-}+\\bar{\\Omega}^{+}$) baryons as well as their anisotropic flows\nin Au+Au collisions at RHIC using a dynamical quark coalescence model that\nincludes the effect due to quark phase-space distributions inside hadrons. With\ncurrent quark masses and fixing the $\\phi $ and $\\Omega $ radii from fitting\nmeasured yields, we first study the ratio of the yield of $\\Omega $ baryons to\nthat of $\\phi $ mesons as well as their elliptic and fourth-order flows as\nfunctions of their transverse momentum. How the elliptic and fourth-order flows\nof $\\phi $ mesons and $\\Omega $ baryons are related to those of strange and\nantistrange quarks is then examined. The dependence of above results on $\\phi $\nand $\\Omega $ radii as well as on the strange quark mass is also studied.",
