Table 4

Abundances of the observed species for IRAS 18095+2704 are presented for a model atmospheres of T_eff = 6700 K, log g = 0.3 (KT), ξ = 6.0 and T_eff = 6500 K, log g = 0.5, ξ = 4.7 (this work). The solar abundances from Asplund et al. (2009) is used to convert Klochkova's abundance of element X to [X/Fe] for comparison purposes.
