摘要: Simultaneous excitation of low-frequency eccentric precessing mode (one-armed p-mode) and tilt on tidally deformed disks is considered. If the orbit secondary star its orbital plane misaligned with disk primary, above-mentioned two oscillation modes are simultaneously excited primary disk, former having prograte precession latter retrograde precession. This oscillations due to a wave-wave resonant process considered by Kato (2013). parameter values relevant Be/X-ray binary systems adopted, periods these around ten times period secondary, which may be comparable time scale giant outbursts observed in systems.
