Tidal interactions play an important role in the evolution and ultimate fate
of compact white dwarf (WD) binaries. Not only do tides affect the pre-merger
state (such as temperature and rotation rate) of the WDs, but they may also
determine which systems merge and which undergo stable mass transfer. In this
paper, we attempt to quantify the effects of rotation on tidal angular momentum
transport in binary stars, with specific calculations applied to WD stellar
models. We incorporate the effect of rotation using the traditional
approximation, in which the dynamically excited gravity waves within the WDs
are transformed into gravito-inertial Hough waves. The Coriolis force has only
a minor effect on prograde gravity waves, and previous results predicting the
tidal spin-up and heating of inspiraling WDs are not significantly modified.
However, rotation strongly alters retrograde gravity waves and inertial waves,
with important consequences for the tidal spin-down of accreting WDs. We
identify new dynamical tidal forcing terms that arise from a proper separation
of the equilibrium and dynamical tide components; these new forcing terms are
very important for systems near synchronous rotation. Additionally, we discuss
the impact of Stokes drift currents on the wave angular momentum flux. Finally,
we speculate on how tidal interactions will affect super-synchronously rotating
WDs in accreting systems.Comment: 18 pages, 7 figure
