A Comparison of p-g Tidal Coupling Analyses

Understand

Two recent studies have attempted to constrain the proposed $p$-$g$ tidal instability with gravitational-wave data from GW170817.

• The studies use Bayesian methods to compare a model that includes $p$-$g$ tidal effects with one that does not.
• Using the same data, they arrive at very different conclusions.
• Reyes & Brown find that the observations of GW170817 strongly disfavor the existence of $p$-$g$ mode coupling.
