Fig. 13.
Depletion of metals in the Bridge relative to hydrogen (upper panel) and oxygen (lower panel). Our sample stars are marked with triangles. Open triangle refers to the upper-limit on the oxygen abundance for MBO2. For comparison, we include abundances of previously analyzed Bridge stars (Rolleston et al. 1999; Lee et al. 2005; Hambly et al. 1994) as circles, and ISM abundances (Lehner et al. 2008, 2001) as squares.
