Subproject A4: The Most Metal-Poor Stars of the Galaxy

Norbert Christlieb (LSW), Hans-Günter Ludwig (LSW)

Our searches for the most metal-poor stars of the Galactic halo will be continued by means of a wide-angle sky survey currently being conducted with the Chinese LAMOST telescope, and using the low-resolution spectra acquired by the Gaia Blue Photometer. We will also carry out non-local thermodynamic equilibrium computations of molecular equilibrium and the populations of molecular energy levels, to derive corrections in particular for carbon abundances determined from CH molecular features.
