Abstract
The effective temperatures of $K^{\pm}$, $\phi$, $\Omega^{-}$ and $\bar{\Omega}^{+}$ produced in Au+Au collisions at RHIC-BES energies are presented. Energy dependence of the kaon effective temperature is approximately constant at lower RHIC-BES energies, similar with previous SPS results and could indicate the onset of deconfinement in this energy range. The centrality dependence of $T_{K^{\pm}}$ showed that the charged kaon effective temperature increases at higher BES energies and also from peripheral to central collisions. The $\phi$ and $\Omega$ effective temperatures increase with energy and no plateau-like behaviour is evidenced by the data.
