Three-dimensional hydrodynamical CO5BOLD model atmospheres of red giant stars II. Spectral line formation in the atmosphere of a giant located near the RGB tip
A. Kucinskas, M. Steffen, H. -G. Ludwig +6
We investigate the role of convection in the formation of atomic and molecular lines in the atmosphere of a red giant star. For this purpose we study the formation properties of sp…
6Li detection in metal-poor stars: can 3D model atmospheres solve the second lithium problem?
M. Steffen, R. Cayrel, E. Caffau +3
The presence of 6Li in the atmospheres of metal-poor halo stars is usually inferred from the detection of a subtle extra depression in the red wing of the 7Li doublet line at 670.8…
A primordial star in the heart of the Lion
E. Caffau, P. Bonifacio, P. François +14
Context: The discovery and chemical analysis of extremely metal-poor stars permit a better understanding of the star formation of the first generation of stars and of the Universe…
Simulations of the solar near-surface layers with the CO5BOLD, MURaM, and Stagger codes
B. Beeck, R. Collet, M. Steffen +6
Radiative hydrodynamic simulations of solar and stellar surface convection have become an important tool for exploring the structure and gas dynamics in the envelopes and atmospher…
