  The spin and parity of the charmed mesons $D_{s}^{*+}$, $D^{*0}$ and $D^{*+}$
are determined for the first time to be $J^P=1^{-}$ with significances greater
than 10$\sigma$ over other hypotheses of $2^{+}$ and $3^{-}$, using an $e^+e^-$
collision data sample with an integrated luminosity of 3.19 fb$^{-1}$ collected
by the BESIII detector at a center-of-mass energy of 4.178 GeV. Different
spin-parity hypotheses for $D_{s}^{*+}$, $D^{*0}$, and $D^{*+}$ mesons are
tested via a helicity amplitude analysis of the processes $e^+e^-\to
D^{*+}_{s}D^{-}_{s}$, $D^{*0}D^{0}$ and $D^{*+}D^{-}$, with $D^{*+}_{s}\to
D^{+}_{s} \gamma$, $D^{*0}\to D^{0}\pi^{0}$, and $D^{*+}\to D^{+}\pi^{0}$. The
results confirm the quark model predictions.
