Evidence for powerful AGN winds at high redshift: Dynamics of galactic outflows in radio galaxies during the "Quasar Era"
N. P. H. Nesvadba, M. D. Lehnert, C. De Breuck +2
AGN feedback now appears as an attractive mechanism to resolve some of the outstanding problems with the "standard" cosmological models, in particular those related to massive gala…
Atmospheric composition and structure of HD209458b
J. -M. Désert, A. Vidal-Madjar, A. Lecavelier des Etangs +4
Transiting planets like HD209458b offer a unique opportunity to scrutinize their atmospheric composition and structure. Transit spectroscopy probes the transition region between th…
Solar twins in M67
L. Pasquini, K. Biazzo, P. Bonifacio +2
The discovery of true solar analogues is fundamental for a better understanding of the Sun and of the solar system. The open cluster M67 offers a unique opportunity to search for s…
The solar photospheric abundance of hafnium and thorium. Results from CO5BOLD 3D hydrodynamic model atmospheres
Elisabetta Caffau, L. Sbordone, H. -G. Ludwig +3
Context: The stable element hafnium (Hf) and the radioactive element thorium (Th) were recently suggested as a suitable pair for radioactive dating of stars. The applicability of t…
NLTE determination of the aluminium abundance in a homogeneous sample of extremely metal-poor stars
S. M. Andrievsky, M. Spite, S. A. Korotin +5
Aims: Aluminium is a key element to constrain the models of the chemical enrichment and the yields of the first supernovae. But obtaining precise Al abundances in extremely metal-p…
Small Dwarf Galaxies Within Larger Dwarfs: Why Some Are Luminous While Most Go Dark
Elena D'Onghia, George Lake
We consider the possibility that the Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. Seven of the eleven…
