Using the CIFIST grid of CO5BOLD 3D model atmospheres to study the effects of stellar granulation on photometric colours. II. The role of convection accross the H-R diagram
A. Kučinskas, J. Klevas, H. -G. Ludwig +3
We studied the influence of convection on the spectral energy distributions, photometric magnitudes, and colour indices of different types of stars across the H-R diagram. The 3D h…
Using the CIFIST grid of CO5BOLD 3D model atmospheres to study the effects of stellar granulation on photometric colours. I. Grids of 3D corrections in the UBVRI, 2MASS, Hipparcos, Gaia, and SDSS systems
P. Bonifacio, E. Caffau, H. -G. Ludwig +9
The atmospheres of cool stars are temporally and spatially inhomogeneous due to the effects of convection.The influence of this inhomogeneity, referred to as granulation, on colour…
TOPoS: I. Survey design and analysis of the first sample
E. Caffau, P. Bonifacio, L. Sbordone +14
The metal-weak tail of the metallicity distribution function (MDF) of the Galactic Halo stars contains crucial information on the formation mode of the first generation of stars. T…
X-Shooter GTO: evidence for a population of extremely metal-poor, alpha-poor stars
E. Caffau, P. Bonifacio, P. Francois +12
The extremely metal-poor stars are the direct descendants of the first generation stars. They carry the chemical signature of the pristine Universe at the time they formed, shortly…
Nitrogen isotopes in AGB carbon stars and presolar SiC grains: a challenge for stellar nucleosynthesis
R. Hedrosa, C. Abia, M. Busso +5
Isotopic ratios of C, N, Si, and trace heavy elements in presolar SiC grains from meteorites provide crucial constraints to nucleosynthesis. A long-debated issue is the origin of t…
Comparative Modelling of the Spectra of Cool Giants
T. Lebzelter, U. Heiter, C. Abia +24
Our ability to extract information from the spectra of stars depends on reliable models of stellar atmospheres and appropriate techniques for spectral synthesis. Various model code…
