The properties of the D*{sub sJ}(2317){sup +} and D{sub sJ}(2460){sup +} mesons are studied using 125 fb{sup -1} of e{sup +}e{sup -} --> c{bar c} data collected by the BaBar experiment. Preliminary mass estimates of [2318.9 {+-} 0.3 (stat.) {+-} 0.9 (syst.)] MeV/c{sup 2} and [2459.4 {+-} 0.3 (stat.) {+-} 1.0 (syst.)] MeV/c{sup 2} are obtained. Searches are performed for the decay to the D{sub s}{sup +} meson along with one or more {pi}{sup 0}, {pi}{sup +}, or {gamma} particles. A search is also performed for neutral and doubly-charged partners.
