$D_s$ mesons are studied in three quantum channels ($J^P=0^+$, $1^+$ and$2^+$), where experiments have identified the very narrow $D_{s0}^*(2317)$,$D_{s1}(2460)$ and narrow $D_{s1}(2536)$, $D_{s2}^*(2573)$. We explore theeffect of nearby $DK$ and $D^*K$ thresholds on the subthreshold states usinglattice QCD. Our simulation is done on two very different ensembles of gaugeconfigurations (2 or 2+1 dynamical quarks, Pion mass of 266 or 156 MeV, latticesize $16^3\times 32$ or $32^3\times 64$). In addition to $\bar{q}q$ operatorswe also include meson-meson interpolators in the correlation functions. Thisclarifies the identification of the states above and below the scatteringthresholds. The ensemble with $m_\pi \simeq 156~$MeV renders the $D_{s1}(2460)$as a strong interaction bound state 44(10)MeV below $D^*K$ threshold, which isin agreement with the experiment. The $D_{s0}^*(2317)$ is found 37(17)MeV below$DK$ threshold, close to experiment value of 45MeV. The narrow resonances$D_{s1}(2536)$ and $D_{s2}^*(2573)$ are also found close to the experimentalmasses.
