Description

Anisotropic flow ($v_n$) measurements can provide important constraints for initial state models and for precision extraction of the temperature dependence of the specific shear viscosity $\eta/s$. Recent STAR measurements for rapidity even dipolar flow $v^{even}_1$ confirm the important influence of momentum conservation, as well as the characteristic dependencies on $\sqrt{s_{NN}}$ , centrality and $p_T$, expected when initial-state geometric fluctuations act in concert with hydrodynamic-like expansion to generate $v^{even}_1$. Dipolar flow measurements will be presented and discussed for a broad range of transverse momenta, $p_T$, and centrality intervals for Au+Au Beam Energy Scan ($\sqrt{s_{NN}}~=~ 7.7~-~200$ GeV), $U+U$ ($\sqrt{s_{NN}}~=~193~GeV$), and Cu+Au, Cu+Cu, d+Au and p+Au ($\sqrt{s_{NN}}~=~200~GeV$) collisions.
