Abundance pattern of the elements in Pisces II 10694 and three other galactic C-rich stars with [Fe/H] = −3.6, −4.0 and −5.7. The abundance pattern of the elements in Pisces II 10694 is very similar to the pattern observed in CS 22949-037 and SDSS J1349+1407. In HE 1327-2326 which has an extremely low metal abundance, the enhancement of C, N, O, Na is stronger and the decrease steeper. In all the stars the abundance of the elements from Ca and heavier is normal. The dashed blue line shows the mean abundance pattern of the elements in Pisces II 10694, CS 22949-037, and SDSS J1349+1407, and the dotted grey line the mean abundance pattern in HE 1327-2326.
