Non-supersymmetric heterotic branes

The common statement that any consistent quantum gravity theory contains dynamical objects with all possible charges suggests that there are still a number of hitherto-unidentified branes in string theory. Here we give the exact worldsheet description of near-horizon limits of non-supersymmetric $p$-branes in ten-dimensional $\mathrm{S}\mathrm{p}\mathrm{i}\mathrm{n}(32)\mathrm{/}{\mathbb{Z}}_2$ or $(E_8\times E_8)⋊{\mathbb{Z}}_2$ heterotic superstring theories for $p=7,6,4,0$.
