Tidal Modulation of Radial Oscillations in Components of Circular-Orbit Close Binaries
Published online by Cambridge University Press: 12 April 2016
Abstract
A theoretical description is presented of the modulation of a radial oscillation in a uniformly rotating star in a close binary that is subject to the tidal action of a companion moving in a circular orbit. The star is assumed to rotate non-synchronously with the companion’s orbital motion. A tidal modulation of a radial oscillation has been observed in the star θ Tucanae by Sterken (1997) and De Mey et al. (1998).
