Abstract: (arXiv)
Lorentzian signature D-branes of all dimensions for the Nappi-Witten string are constructed. This is done by rewriting the gluing condition J+=FJJ_+=FJ_- for the model chiral currents on the brane as a well posed first order differential problem and by solving it for Lie algebra isometries FF other than Lie algebra automorphisms. By construction, these D-branes are not twined conjugacy classes. Metrically degenerate D-branes are also obtained.
