Abundances in Galaxies

Abstract

To start things going, the following topics were suggested:*

• 1. Reliability of abundances

  • Stars vs H ii regions

  • H ii classical diagnostics

  • Effects of shocks and inhomogeneities on H ii-region diagnostics

  • H n new diagnostics

  • Can reliable H ii-region diagnostics be developed for high metallicity?

  • Y _p and dY/dZ

  • nLTE and inhomogeneity in stellar atmospheres

  • O/Fe

  • X-ray abundances

  • Abundance inhomogeneities

  • Division between galaxies and 1GM

  • What is the yield?**

  • SFR history and IMF

  • Z(L) relation for galaxies; origin of scatter

  • dG problem

  • Thick/thin disk dichotomy

  • Field stars versus globular clusters

  • Mg/Fe in E-galaxies

  • Rates of galactic evolution

  • Does SFR(z) account for existing stars and cosmic chemical evolution?

  • Nature and chemistry of DLA systems

  • Composition of Lyman break galaxies

• 2. Inventory of heavy elements in the universe

  • Division between galaxies and 1GM

  • What is the yield?**

• 3. Population effects and global galactic properties

  • SFR history and IMF
