Vast majority of triple systems compatible with the “merger in a triple” scenario has a probability of being dynamically unstable ≳90%. For each observed binary, we show the fraction of compatible putative triple progenitors that has a probability of being disrupted larger than the x coordinate according to the “ghost orbit” method of Vynatheya et al. (2023). Orange and blue curves correspond to the two values of fractional mass loss at merger f_Δ = 0 and 1 assumed. The distribution is marginalized over all parameters defining the architecture of the triples compatible with the present-day binaries (see text).
