The most metal-poor stars of the Galaxy (A04)

• Subject Area: Astrophysics and Astronomy
• Term: from 2011 to 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 138713538

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 by 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 in order to derive corrections in particular for carbon abundances determined from CH molecular features.
