In previous work, we found ten-dimensional solutions to the supergravity equations of motion with a dS4 factor and O8-planes. We generalize this analysis and obtain other solutions in the same spirit, with an O8+ and an O6−. We examine our original solutions in more detail, focusing in particular on the O8− singularities and on the issues created by their boundary conditions. We also point out some previously known super- symmetric AdS solutions with the same local behavior at their O8− singularity.

Abstract
In previous work, we found ten-dimensional solutions to the supergravity equations of motion with a dS4 factor and O8-planes. We generalize this analysis and obtain other solutions in the same spirit, with an O8+ and an O6−. We examine our original solutions in more detail, focusing in particular on the O8− singularities and on the issues created by their boundary conditions. We also point out some previously known super- symmetric AdS solutions with the same local behavior at their O8− singularity.
