Dynamic Tides in Close Binaries
The basic theory of dynamic tides in close binaries is reviewed. Particular attention is paid to resonances between dynamic tides and free oscillation modes and to the role of the apsidal-motion rate in probing the internal structure of binary components. The discussed effects are generally applicable to stars across the entire Hertzsprung-Russell diagram, including the binary OB-stars discusse...
متن کاملAsymptotic representation of low-frequency dynamic tides in close binaries
An asymptotic representation of low-frequency dynamic tides in close binaries is developed. The dynamic tides are treated as low-frequency, linear, isentropic, forced oscillations of a non-rotating spherically symmetric star. The asymptotic representation is developed to the second order in the forcing frequency. For the sake of simplification, the star is assumed to be everywhere in radiative ...
متن کاملNonadiabatic resonant dynamic tides and orbital evolution in close binaries
This investigation is devoted to the effects of nonadiabatic resonant dynamic tides generated in a uniformly rotating stellar component of a close binary. The companion is considered to move in a fixed Keplerian orbit, and the effects of the centrifugal force and the Coriolis force are neglected. Semi-analytical solutions for the linear, nonadiabatic resonant dynamic tides are derived by means ...
متن کاملThe asymptotic representation of dynamic tides in close binaries revisited
The asymptotic representation of low-frequency, linear, isentropic dynamic tides in components of close binaries derived by Smeyers (1997) is reconsidered. The constructions of the second-order boundary-layer solutions for the divergence and the radial component of the tidal displacement are made more transparent. Moreover, the determination of the constants involved in the second-order boundar...
متن کاملResonant dynamic tides and apsidal motion in close binaries
The resonance of a dynamic tide with a free oscillation mode in a component of a close binary system of stars is treated by means of a two-time variable expansion procedure. The treatment is developed with respect to a frame of reference corotating with the star. Both the free oscillation mode and the dynamic tide are considered as linear, isentropic perturbations of a spherically symmetric sta...
