Mass-ratio growth as function of the initial binary mass ratio calculated over the simulated 1000 P_b. The blue, violet, and pink stars show our results for e₀ = 0.05, e₀ = 0.5, and e₀ = 0.8, respectively. The orange dotted line shows the result obtained for circular binaries by Duffell et al. (2020), while the pink solid line shows the result obtained for binaries with e_b = 0.8 by Siwek et al. (2023b). The grey dots show the values obtained by Dittmann & Ryan (2021) for circular binaries.
