Model Atmospheres From Very Low Mass Stars to Brown Dwarfs
F. Allard, D. Homeier, B. Freytag
Since the discovery of brown dwarfs in 1994, and the discovery of dust cloud formation in the latest Very Low Mass Stars (VLMs) and Brown Dwarfs (BDs) in 1996, the most important c…
Galactic Evolution of Oxygen: OH lines in 3D hydrodynamical model atmospheres
J. I. Gonzalez Hernandez, P. Bonifacio, H. -G. Ludwig +3
The measurement of oxygen lines in metal-poor unevolved stars, in particular near-UV OH lines, can provide invaluable information on the properties of the Early Galaxy. Near-UV OH…
Implicit hydrodynamic simulations of stellar interiors
Maxime Viallet, Isabelle Baraffe, Cedric Mulet-Marquis +4
We report on the development of an implicit multi-D hydrodynamic code for stellar evolution. We present two test-cases relevant for the first scientific goal of the code: the simul…
The role of convection, overshoot, and gravity waves for the transport of dust in M dwarf and brown dwarf atmospheres
Bernd Freytag, France Allard, Hans-Guenter Ludwig +2
Observationally, spectra of brown dwarfs indicate the presence of dust in their atmospheres while theoretically it is not clear what prevents the dust from settling and disappearin…
The solar photospheric abundance of carbon.Analysis of atomic carbon lines with the CO5BOLD solar model
E. Caffau, H. -G. Ludwig, P. Bonifacio +5
The use of hydrodynamical simulations, the selection of atomic data, and the computation of deviations from local thermodynamical equilibrium for the analysis of the solar spectra…
