Predictions of tidal interactions in the WASP-4 system, shown as an illustrative example of our modelling outcome. The first column shows the histogram of Q′_WB values. The second column shows the evolution of Q′_WB, with the top panel zoomed in around the 1σ age estimate. Each line corresponds to one realisation of stellar parameters. Black lines indicate phases when the host’s core is convective, grey lines mark phases when the host’s core is radiative but wave breaking is not expected, and blue lines denote phases when the host’s core is radiative and wave breaking occurs. The estimated Q′_WB with uncertainties is shown above the column. The third column shows the evolution of M_crit, with red lines indicating phases when the host’s core is radiative and wave breaking occurs. The estimated probability of wave breaking is shown above the column. The fourth column presents the evolution of Ṗ, with green lines marking phases when the host s core is radiative and wave breaking occurs. The estimated value of Ṗ with uncertainties is displayed above the column.
