We study the tidal excitation of gravity modes (g-modes) in compact white dwarf binary systems with periods ranging from minutes to hours. As the orbit of the system decays via gravitational radiation, the orbital frequency increases and sweeps through a series of resonances with the g-modes of the white dwarf. At each resonance, the tidal force excites the g-mode to a relatively large amplitude, transferring the orbital energy to the stellar oscillation. We calculate the eigenfrequencies of g… Expand

Polygram Stars: Resonant Tidal Excitation of Fundamental Oscillation Modes in Asynchronous Stellar Coalescence
The prevalence of binary stars at close separations implies that many of these systems will interact or merge during the binary's lifetime. This paper presents hydrodynamic simulations of theExpand
Tidal resonance locks in inspiraling white dwarf binaries
We calculate the tidal response of helium and carbon/oxygen (C/O) white dwarf (WD) binaries inspiraling due to gravitational wave emission. We show that resonance locks, previously considered inExpand

Inverse tides in pulsating binary stars
In close binary stars, the tidal excitation of pulsations typically dissipates energy, causing the system to evolve towards a circular orbit with aligned and synchronized stellar spins. However, forExpand

Dynamically formed compact object binaries may still be eccentric while in the LIGO/Virgo band. For a neutron star (NS) in an eccentric binary, the fundamental modes (f-modes) are excited atExpand


Resonant excitation of white dwarf oscillations in compact object binaries – I. The no back reaction approximation
We consider the evolution of white dwarfs with compact object companions (specifically black holes with masses up to ∼10^6 M_⊙, neutron stars, and other white dwarfs). We suppose that the orbits areExpand
Energy Dissipation Through Quasi-static Tides in White Dwarf Binaries
