Different experiments have confirmed that the $D_{s0}^{\ast}(2317)$ and$D_{s1}(2460)$ mesons are very narrow states located, respectively, below the$DK$ and $D^{\ast}K$ thresholds. This is markedly in contrast with theexpectations of naive quark models and heavy quark symmetry. We address themass shifts of the $c\bar{s}$ ground states with quantum numbers $J^{P}=0^{+}$($D_{s0}^{\ast}(2317)$) and $J^{P}=1^{+}$ ($D_{s1}(2460)$) using anonrelativistic constituent quark model in which quark-antiquark andmeson-meson degrees of freedom are incorporated. The quark model has beenapplied to a wide range of hadronic observables and thus the model parametersare completely constrained. We observe that the coupling of the $0^{+}$$(1^{+})$ meson sector to the $DK$ $(D^{\ast}K)$ threshold is a key feature inlowering the masses of the corresponding $D_{s0}^{\ast}(2317)$ and$D_{s1}(2460)$ states predicted by the naive quark model, but also indescribing the $D_{s1}(2536)$ meson as the $1^{+}$ state of the$j_{q}^{P}=3/2^{+}$ doublet predicted by heavy quark symmetry and thusreproducing its strong decay properties. Two features of our formalism cannotbe address nowadays by other approaches: the coupling of the $D$-wave$D^{\ast}K$ threshold in the $J^{P}=1^{+}$ $c\bar{s}$ channel and thecomputation of the probabilities associated with different Fock components inthe physical state.
