Notes. These timescales take into account the time needed to form the first giant planet in the simulations of Ledda et al. (2023) (see its Tables A.6 and A.9) and the time needed to reach a stable configuration in our simulations; t_merge is taken from Table 1 of Ledda et al. (2023). The shortest and longest times (top) are calculated accounting for the whole set of performed simulations (500 for each DWD); The shortest and longest times (bottom) are only relative to the specific system 126 and 235, which experienced the largest positive CoM shift among the nominal, nonresonant, simulations.
