Chemical composition of globular cluster and halo post-agb stars

We present results of model atmosphere analyses of two post-AGB stars, ZNG-1 in the globular cluster M10 andthe halo star PG1704+222. A di erential abundance analysis reveals typical post-AGB abundance patterns,both stars being generally metal poor with approximately solar He. Large C depletions, ob...
