Table 2
Metallicities [Fe/H], and A(X) = log(NX∕NH) + 12 of the elements for the 7 neutron-capture elements of the first peak (+A(Ba) and A(Eu)) derived from LTE computations in our 11 “LP first stars”.

Notes. In column 1 lists the identification number ID of the star, also included in Figure 4B. ID=1 is for the star with the lowest [Sr/Ba] ratio and ID=11 for the star with the highest [Sr/Ba] ratio (see [Sr/Ba] in Table 3). At the end of the table, we give the abundances of these elements in the peculiar C-rich star CS 22949-037 and in the classical r-rich and r-poor stars CS 31082-001 and HD 122563. (*)The solar abundances A(X)⊙ are taken from Lodders et al. (2009).
