“Our results demonstrate that even intermediate-mass protoplanets — less detectable, but more ubiquitous, than super-Jupiters — are capable of indirectly inducing large-scale spiral disk features, and underscore the importance of including radiation physics in efforts to reproduce observations.” Reference: Can gap-edge illumination excite spirals in protoplanetary disks?
