By relaxing the regularity conditions imposed in arXiv:1107.1722 on half-BPS solutions to six-dimensional Type~4b supergravity, we enlarge the space of solutions to include two new half-BPS configurations, which we refer to as the \kap and the \funnel. We give evidence that the \kap and \funnel can be interpreted as fully back-reacted brane solutions with respectively AdS2 and AdS2× S2 world volumes. \kap and \funnel solutions with a single asymptotic AdS3 × S3 region are constructed analytically. We argue that \kap solutions provide simple examples of holographic duals to boundary CFTs in two dimensions and present calculations of their holographic boundary entropy to support the BCFT dual picture.
