Long Photometric Cycles in Double-periodic Variables from Nodal Precession of a Tilted Accretion Disk

We investigate whether the long photometric cycles observed in double-periodic variables (DPVs) can arise from nodal precession of a tilted accretion disk driven by the tidal torque of the companion. Within a simple analytical framework, we derive testable relations linking the long-to-orbital perio...
