Comparison of the isotopic ratios of C, N, O, S, Si, and Cl measured at z = 0.89 toward PKS 1830−211(SW) (Muller et al. 2006, 2011, 2013 and this work) and in the solar system (solar symbols in green, Lodders 2003), and predictions from evolution models from Kobayashi et al. (2011) (black squares) for the solar neighbourhood (solar, at [Fe/H]=−2.6, −1.1, and −0.5), and halo and bulge at [Fe/H]=−0.5. The ¹⁴N/¹⁵N and ¹⁶O/¹⁸O ratios are normalized by the ¹²C/¹³C ratio, because of the difficulties of measuring all three separately in the z = 0.89 absorber toward PKS 1830−211.
