**Abstract:**

*We apply heavy hadron chiral perturbation theory (HHChPT) to study the properties of the even- and odd-parity charmed-strange mesons. We find that the experimental masses and electromagnetic decay rates are consistent with HHChPT.We consider the hypothesis that the even-parity states are molecules. An RG analysis shows that once the HHChPT parameter set overlaps with the parity doubling model, the parameters remain at those values. Finally, the implications for the bottom-strange system are described.*
