We also describe how, in the SO(16) × Accepted 21 February 2017 SO(16) heterotic model, if the torus vacuum energy is taken into account, unbounded seven-form Available online 28 February 2017 fluxes can support similar AdS7 × S3 vacua, while unbounded three-form fluxes, when combined with Editor: N. Lambert internal gauge fields, can support AdS3 × S7 vacua, which continue to be available even if is neglected. In addition, special gauge field fluxes can support, in the SO(16) × SO(16) heterotic model, a set of AdSn × S10−n vacua, for all n = 2, .., 8. String loop and α corrections appear under control when large form fluxes are allowed. © 2017 The Author(s).
