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…
Unidentified Gamma-Ray Sources as Ancient Pulsar Wind Nebulae
O. C. de Jager, S. E. S. Ferreira, A. Djannati-Ataï +6
In this paper we explore the evolution of a PWN while the pulsar is spinning down. An MHD approach is used to simulate the evolution of a composite remnant. Particular attention is…
The ESO Large Programme First Stars
P. Bonifacio, J. Andersen, S. Andrievsky +19
In ESO period 65 (April-September 2000) the large programme 165.N-0276, led by Roger Cayrel, began making use of UVES at the Kueyen VLT telescope. Known within the Team and outside…
