Average rpTDE fraction in the loss-cone channel is insensitive to the stellar type or the exact loss-cone boundary βrpTDE. The four “diagonal” lines are obtained from Equations (18) and (19). In addition, dynamical tides may drive stars from a larger “initial” orbital period Tobt,i to a shorter orbital period Tobt, where the stars repeatedly get disrupted and are observed. As a result, dynamical tides increase the rate of observable rpTDEs by a factor of a few (see Section 2.5). Here the thick blue line is obtained from the light blue line by assuming Tobt = Tobt,i/10.
