| Summary:

A uniform construction of non-supersymmetric 0-, 4-, 6- and 7-branes in
heterotic string theory was announced and outlined in our letter
cite{Kaidi:2023tqo}. In this full paper, we provide details on their
properties. Among other things, we discuss the charges carried by the branes,
their topological and dynamical stability, the exact worldsheet descriptions of
their near-horizon regions, and the relationship of the branes to the
mathematical notion of topological modular forms.
