  We present results on systematic measurements of strange and multi-strange
particles with the STAR detector for center of mass energies per nucleon pair
of 62.4 and 200 GeV in ultra-relativistic Au+Au collisions at RHIC. We use
these results to characterize the chemical and kinetic freeze-out properties of
the fireball produced by the collision. This is done by comparison to
statistical and hydrodynamical models as well as parameterization. We emphasize
particularly the energy dependence of these features comparing measurements
obtained at RHIC with different energies but also at the lower energies
available at the SPS.
