Scientific paper

Model atmosphere analyses are presented for high-resolution spectra of four stars at high Galactic latitudes. Although their derived atmospheric parameters are consistent with their previous classification as early B-type stars, their chemical compositions are significantly different from those expected for Population I objects. However both the chemical compositions and atmospheric parameters appear to be consistent with a post-asymptotic giant branch evolutionary status.
