Dynamical resonance locking in tidally interacting binary systems
Joshua Burkart, Eliot Quataert, Phil Arras
We examine the dynamics of resonance locking in detached, tidally interacting binary systems. In a resonance lock, a given stellar or planetary mode is trapped in a highly resonant…
It takes a village to raise a tide: nonlinear multiple-mode coupling and mode identification in KOI-54
Ryan M. O'Leary, Joshua Burkart
We explore the tidal excitation of stellar modes in binary systems using Kepler observations of the remarkable eccentric binary KOI-54 (HD 187091; KIC 8112039), which displays stro…
An instability due to the nonlinear coupling of p-modes to g-modes: Implications for coalescing neutron star binaries
Nevin N. Weinberg, Phil Arras, Joshua Burkart
A weakly nonlinear fluid wave propagating within a star can be unstable to three-wave interactions. The resonant parametric instability is a well-known form of three-wave interacti…
Tidal resonance locks in inspiraling white dwarf binaries
Joshua Burkart, Eliot Quataert, Phil Arras +1
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…
Tidal asteroseismology: Kepler's KOI-54
Joshua Burkart, Eliot Quataert, Phil Arras +1
We develop a general framework for interpreting and analyzing high-precision lightcurves from eccentric stellar binaries. Although our methods are general, we focus on the recently…
The Radial Velocity Signature of Tides Raised in Stars Hosting Exoplanets
Phil Arras, Joshua Burkart, Eliot Quataert +1
Close-in, massive exoplanets raise significant tides in their stellar hosts. We compute the radial velocity (RV) signal due to this fluid motion in the equilibrium tide approximati…
