Empty gaps? Depleting annular regions in debris discs by secular resonance with a two planet system

Empty gaps? Depleting annular regions in debris discs by secular resonance with a two planet system

... In this paper, we will consider a scenario in which there are multiple planets interior to the disc (i.e. within 30au), sculpting the disc via their secular resonances – these reso- nances are important for understanding ...
