Table 2.
Young α-rich stars (YAR) in different bins of metallicity.
| [Fe/H] | TOT | HA | YAR | fTOT | fHA |
|---|---|---|---|---|---|
| > −0.25 | 3335 (3021) | 344 (302) | 25 (24) | 0.7 % (0.7 %) |
7.3 % (7.9 %) |
| [ − 0.5, −0.25] | 2200 (1866) | 1069 (875) | 70 (85) | 3.2 % (4.6 %) |
6.5 % (9.7 %) |
| < −0.5 | 1338 (998) | 1115 (835) | 73 (97) | 5.5 % (9.7 %) |
6.5 % (11.6 %) |
Notes. Listed are the following: first column, the considered range in [Fe/H]; second, third, and fourth columns, the corresponding total number of stars, high-α stars, and young α-rich stars, respectively; fifth and sixth columns, the fraction of young α-rich stars with respect to the total of stars and with respect to the high-α sequence, respectively. We report our results for ages computed with (νmax, L) and, in parentheses, with (νmax, Δν).
