\begin{document}$ D^*_{(s)} $\end{document} mesons can provide a platform to verify the standard model, explore new physics, and understand the mechanisms of weak interactions. At present, the theoretical and experimental studies on \begin{document}$ D^*_{(s)} $\end{document} mesons are relatively limited. In addition to the dominant electromagnetic decays, the \begin{document}$ D^*_{(s)} $\end{document} weak decays should be feasible to explore the \begin{document}$ D^*_{(s)} $\end{document} mesons. In this study, we used the covariant light-front quark model to study the form factors of the transitions \begin{document}$ D^*_{(s)}\to \pi, K, \eta_{q, s} $\end{document}, and then calculated the branching ratios of the semi-leptonic decays \begin{document}$ D^*_{(s)}\to P\ell^{+}\nu_{\ell} $\end{document} and the non-leptonic decays \begin{document}$ D^*_{(s)}\to PP, PV $\end{document} with \begin{document}$ P=\pi, K, \eta^{(\prime)}, $\end{document}\begin{document}$ V=\rho, K^*, \phi $\end{document}, and \begin{document}$ \ell=e, \mu $\end{document}. The channels \begin{document}$ D_{s}^{*+}\to\eta \ell^{+}\nu_{\ell} $\end{document} and \begin{document}$ D^{*+}_{s}\to \eta\rho^{+} $\end{document} possess the largest branching ratios, which can reach an order of \begin{document}$ 10^{-6} $\end{document} among these decays, and are most likely to be accessible in experiments at future high-luminosity colliders. Furthermore, we predict and discuss the longitudinal polarization fraction \begin{document}$ f_{\rm L} $\end{document} and the forward-backward asymmetry \begin{document}$ A_{\rm FB} $\end{document} for the considered semi-leptonic \begin{document}$ D^*_{(s)} $\end{document} decays."> <inline-formula><tex-math id="M1">\begin{document}$ {{\boldsymbol D}^*_{ {({\boldsymbol s})}}{\bf\to} {\boldsymbol P} }$\end{document}</tex-math><alternatives><graphic specific-use="online" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/2d643e50-d175-4ee1-9b7a-e9306c861353/CPC-2025-0452_M1.jpg"/><graphic specific-use="print" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/2d643e50-d175-4ee1-9b7a-e9306c861353/CPC-2025-0452_M1.png"/></alternatives></inline-formula> form factors and their applications to semi-leptonic and non-leptonic weak decays -
