\begin{document}$B^{*}_{u,d,s}$\end{document} and \begin{document}$B_{c}^{*}$\end{document} are investigated within the covariant light-front quark model (CLFQM). By calculating the form factors of the transitions \begin{document}$B_{u, d, s, c}^{*}\to P$\end{document} under the CLFQM, with P denoting a pseudoscalar meson, i.e., \begin{document}$\pi, K, \eta_c(1S,2S), D_{(s)}, B_{(s)}$\end{document}, we predict and discuss several physical observables, including the branching ratios, polarization fractions \begin{document}$f_{L}, f_{\|}$\end{document} , and forward-backward asymmetries \begin{document}$A_{FB}$\end{document}. The total widths of the single-photon radiative decay channels for these b-flavor vector mesons are estimated using their partial widths. In these considered decays, one can find that the semileptonic decays \begin{document}$B_{s}^{*0}\to D_{s}^{-}\ell^{\prime+}{\nu}_{\ell^\prime}$\end{document} and \begin{document}$B_{c}^{*+}\to B_{s}^{0}\ell^{\prime+}{\nu}_{\ell^\prime}, \eta_{c}\ell^{\prime+}{\nu}_{\ell^\prime}$\end{document} , with \begin{document}$\ell^\prime$\end{document} being e or \begin{document}$\tau$\end{document}, and the nonleptonic channels \begin{document}$B_{c}^{*+}\to $\end{document}\begin{document}$ B^0_{s} \pi^{+}, B^0_{s} \rho^{+}$\end{document} have the largest branching ratios, which can reach up to the 10-7 order, and are most likely to be accessible at the future high-luminosity LHCb and Belle-II experiments."> Semileptonic and nonleptonic decays of <inline-formula><tex-math id="Z-20240927092501">\begin{document}${\boldsymbol B^{*}_{\boldsymbol {u,d,s}} }$\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/7c74c5f0-4764-4c13-a500-ea9ce24c6721/CPC-2024-0427_Z-20240927092501.jpg"/><graphic specific-use="print" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/7c74c5f0-4764-4c13-a500-ea9ce24c6721/CPC-2024-0427_Z-20240927092501.png"/></alternatives></inline-formula> in the covariant light-front approach -
