The photospheric solar oxygen project: I. Abundance analysis of atomic lines and influence of atmospheric models
Elisabetta Caffau, Hans-G. Ludwig, Matthias Steffen +5
The solar oxygen abundance has undergone a major downward revision in the last decade, the most noticeable one being the update including 3D hydrodynamical simulations to model the…
The solar photospheric abundance of europium. Results from CO5BOLD 3-D hydrodynamical model atmospheres
A. Mucciarelli, E. Caffau, B. Freytag +2
Context. Europium is an almost pure r-process element, which may be useful as a reference in nucleocosmochronology. Aims. To determine the photospheric solar abundance using CO5BOL…
Atmospheric dynamics of red supergiant stars and applications to Interferometry
A. Chiavassa, B. Plez, E. Josselin +1
We have written a 3D radiative transfer code that computes emerging spectra and intensity maps. We derive from radiative hydrodynamic (RHD) simulations of RSG stars carried out wit…
Convective and non-convective mixing in AGB stars
Falk Herwig, Bernd Freytag, Tyler Fuchs +5
We review the current state of modeling convective mixing in AGB stars. The focus is on results obtained through multi-dimensional hydrodynamic simulations of AGB convection, both…
First local helioseismic experiments with CO5BOLD
O. Steiner, G. Vigeesh, L. Krieger +3
With numerical experiments we explore the feasibility of using high frequency waves for probing the magnetic fields in the photosphere and the chromosphere of the Sun. We track a p…
The Evolution of Central Stars of Planetary Nebulae
Falk Herwig, Bernd Freytag, Klaus Werner
The evolution of central stars of planetary nebulae can proceed in several distinct ways, either leading to H-deficiency or to H-normal surface composition. Several new simulations…
