3D hydrodynamical simulations of stellar photospheres with the CO5BOLD code: photometric colors of a late-type giant
A. Kucinskas, H. -G. Ludwig, E. Caffau +1
We present synthetic broad-band photometric colors of a late-type giant located close to the RGB tip (T_eff = 3640 K, log g = 1.0 and [M/H] = 0.0). Johnson-Cousins-Glass BVRIJHK co…
Solar abundances and granulation effects
E. Caffau, H. -G. Ludwig, M. Steffen
The solar abundances have undergone a major downward revision in the last decade, reputedly as a result of employing 3D hydrodynamical simulations to model the inhomogeneous struct…
Effects of granulation on neutral copper resonance lines in metal-poor stars
P. Bonifacio, E. Caffau, H. -G. Ludwig
We make use of three dimensional hydrodynamical simulations to investigate the effects of granulation on the Cu I lines of Mult. 1 in the near UV, at 324.7 nm and 327.3 nm. These l…
Micro- and macroturbulence derived from 3D hydrodynamical stellar atmospheres
M. Steffen, H. -G. Ludwig, E. Caffau
The theoretical prediction of micro- and macroturbulence (xi_mic and xi_mac) as a function of stellar parameters can be useful for spectroscopic work based on 1D model atmospheres…
The CIFIST 3D model atmosphere grid
H. -G. Ludwig, E. Caffau, M. Steffen +3
Grids of stellar atmosphere models and associated synthetic spectra are numerical products which have a large impact in astronomy due to their ubiquitous application in the interpr…
