Sustained Kozai–Lidov Oscillations in Misaligned Circumstellar Gas Disks

A disk around one component of a binary star system with sufficiently high inclination can undergo Kozai-Lidov (KL) oscillations during which the and eccentricity are exchanged. Previous studies show that without source accretion, KL unstable disks exhibit damped oscillations, due to viscous dissipation, leave stable near or below critical for oscillations. With three-dimensional hydrodynamical simulations we highly misaligned circumbinary flows onto components forms inclined circumstellar each component. We continuous infall material allows continue.
