Enhanced methods for computing spectra from CO5BOLD models using Linfor3D. Molecular bands in metal-poor stars
A. J. Gallagher, M. Steffen, E. Caffau +3
Molecular features such as the G-band, CN-band and NH-band are important diagnostics for measuring a star's carbon and nitrogen abundances, especially in metal-poor stars where ato…
TOPoS: III. An ultra iron-poor multiple CEMP system
E. Caffau, P. Bonifacio, M. Spite +15
One of the primary objectives of the TOPoS survey is to search for the most metal-poor stars. Our search has led to the discovery of one of the most iron-poor objects known, SDSS\,…
Abundances in a sample of turnoff and subgiant stars in NGC 6121 (M4)
Monique Spite, Francois Spite, Andrew J. Gallagher +4
{The aim of this work is to investigate the relations between the abundances of different elements in the globular cluster M4, selected for its uniform deficiency of iron, to explo…
An in-depth spectroscopic examination of molecular bands from 3D hydrodynamical model atmospheres I. Formation of the G-band in metal-poor dwarf stars
A. J. Gallagher, E. Caffau, P. Bonifacio +3
Recent developments in the three-dimensional (3D) spectral synthesis code Linfor3D have meant that, for the first time, large spectral wavelength regions, such as molecular bands,…
