Summary of the predictions of different gas expulsion scenarios for the most robust observational quantities.
| Cluster model | rh, tl[ pc] | NA + ,tl, obs | NA + ,tl, obs/NA + ,cl | MF tail |
|---|---|---|---|---|
| SFE = 1/3 fast GE | 150 pc − 350 pc | 40−170 | 0.7−2.7 | Canonical |
| SFE = 2/3 fast GE | 100 pc − 200 pc | 4−11 | 0.05−0.15 | Canonical |
| SFE = 1/3 slow GE | 40 pc − 100 pc | 1−4 | 0.02−0.07 | Canonical |
| SFE = 1 | < 20 pc − < 90 pc | < 1 − < 2 | < 0.02 | depleted in stars of m ≳ 1 M⊙ |
Notes. The quantities are tidal tail half-number radius, rh, tl, as traced by A stars; number of A stars and earlier in the tidal tail, NA + ,tl, obs, located above the contamination thresholds (NA + ,tl, obs = pANA + ,tl) and thus observable; ratio of the observable A stars and earlier in the tail to those in the cluster, NA + ,tl, obs/NA + ,cl; and shape of the present-day tail MF. The lower (upper) bounds were obtained by taking the minima (maxima) of corresponding quantities in Table 3 for the upper (lower) estimate of the contamination threshold for A stars. The ratio NA + ,tl, obs/NA + ,cl is based on NA, tl/NA, cl in Table 2 assuming that all A stars and earlier in the cluster are observed.
