Query: Beam-Energy Dependence of Directed Flow of $\Lambda$, $\bar{\Lambda}$,
  $K^\pm$, $K^0_s$ and $\phi$ in Au+Au Collisions   Rapidity-odd directed flow measurements at midrapidity are presented for
$\Lambda$, $\bar{\Lambda}$, $K^\pm$, $K^0_s$ and $\phi$ at $\sqrt{s_{NN}} =$
7.7, 11.5, 14.5, 19.6, 27, 39, 62.4 and 200 GeV in Au+Au collisions recorded by
the STAR detector at the Relativistic Heavy Ion Collider. These measurements
greatly expand the scope of data available to constrain models with differing
prescriptions for the equation of state of quantum chromodynamics. Results show
good sensitivity for testing a picture where flow is assumed to be imposed
before hadron formation and the observed particles are assumed to form via
coalescence of constituent quarks. The pattern of departure from a
coalescence-inspired sum-rule can be a valuable new tool for probing the
collision dynamics.
