N2 - Here we present initial studies of two-dimensional angular correlations of Lambda, Lambda, and K-Short(0) triggers with unidentified charged hadrons in Au+Au collisions at root s(NN)=200 GeV measured by STAR. Distributions of pseudo-rapidity difference, Delta eta, and azimuthal separation, Delta phi, are constructed containing structures observed in unidentified hadron correlations, including a jet peak at small Delta eta-Delta phi accompanied by a flow-like ridge extended over Delta eta. These features are studied as a function of centrality via integrated yields and fitting to projections onto Delta eta and Delta phi axes. Yields are found to be consistent with unidentified correlation analyses, and no clear distinction is observed between the three species.
