Dynamical Tides in Rotating Binary Stars
We study the effect of rotation on the excitation of internal oscillation modes of a star by the external gravitational potential of its companion. Unlike the nonrotating case, there are difficulties with the usual mode decomposition for rotating stars because of the asymmetry between modes propagating in the direction of rotation and those propagating opposite to it. For an eccentric binary sy...
متن کاملA dynamical picture of the oceanic tides
A detailed treatment of tide-generating forces is given, followed by a simplified dynamic theory of tidal waves. To clarify the underlying physics, we use a simple model of the ocean that consists of a water shell of uniform depth completely covering the globe. The treatment is appropriate for college and university undergraduate students studying introductory geophysics or astronomy, general p...
متن کاملDynamical Tides in Compact White Dwarf Binaries: Influence of Rotation
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 transpor...
متن کاملPhysics of bodily tides in terrestrial planets and the appropriate scales of dynamical evolution
[1] Any model of tides is based on a specific hypothesis of how lagging depends on the tidal-flexure frequency c. For example, Gerstenkorn (1955), MacDonald (1964), and Kaula (1964) assumed constancy of the geometric lag angle d, while Singer (1968) and Mignard (1979, 1980) asserted constancy of the time lag Dt. Thus each of these two models was based on a certain law of scaling of the geometri...
متن کاملThe Physics of Bodily Tides in Terrestrial Planets, and the Appropriate Scales of Dynamical Evolution
Any model of tides is based on a specific hypothesis of how lagging depends on the tidalflexure frequency χ. For example, Gerstenkorn (1955), MacDonald (1964), and Kaula (1964) assumed constancy of the geometric lag angle δ , while Singer (1968) and Mignard (1979, 1980) asserted constancy of the time lag ∆t . Thus, each of these two models was based on a certain law of scaling of the geometric ...
