Table 5
Frequency of JL planets.
| Cluster | Stars PMa | Stable | Fraction | Detected | Dyn | Total | Neff | Freq. |
|---|---|---|---|---|---|---|---|---|
| stable | JL comp | JL comp | ||||||
| Ursa Major | 54 | 30 | 0.69 | 1 | 1 | 12.51 | 0.08±0.08 | |
| Coma Berenices | 52 | 36 | 0.48 | 1 | 1 | 6.81 | 0.15±0.14 | |
| Hyades | 143 | 68 | 0.69 | 1 | 3 | 4 | 20.68 | 0.19±0.09 |
Notes. First column is the cluster name. Second column the number of stars having the PMa value (Kervella et al. 2022). Third columns give those stars with PMa value for which the orbit of a JL planet can be stable. Column 4 gives the fraction of the stars with potentially stable orbit of JL planets. Column 5 gives the number of planets detected in HCI. Column 6 the number of planets detected though the PMa value. Column 7 the total number of planets to be considered for derivation of the planet frequency. Column 8 gives Neff that is the effective number of stars for which JL planets would be detectable. Column 9 gives the fraction of stars with JL planets.
