Solar photospheric spectrum microvariability III. Radial velocities and line profiles in magnetic active-region granulation
Dainis Dravins, Hans-Günter Ludwig, Matthias Steffen +2
Finding low-mass planets around solar-type stars requires to understand the physical variability of the host star, which greatly exceeds the planet-induced radial-velocity modulati…
The metal-poor end of the Spite plateau. II. Detailed chemical investigation
A. Matas Pinto, M. Spite, E. Caffau +7
Context. The study of old, metal-poor stars deepens our knowledge on the early stages of the universe. In particular, the study of these stars gives us a valuable insight into the…
The solar gravitational redshift from HARPS-LFC Moon spectra. A test of the General Theory of Relativity
J. I. González Hernández, R. Rebolo, L. Pasquini +15
The General Theory of Relativity predicts the redshift of spectral lines in the solar photosphere, as a consequence of the gravitational potential of the Sun. This effect can be me…
TOPoS V: Abundance ratios in a sample of very metal-poor turn-off stars
P. François, E. Caffau, P. Bonifacio +12
Extremely metal-poor stars are keys to understand the early evolution of our Galaxy. The ESO large programme TOPoS has been tailored to analyse a new set of metal-poor turn-off sta…
Abundance of zinc in the red giants of Galactic globular cluster 47 Tucanae
A. Černiauskas, A. Kučinskas, J. Klevas +4
We investigate possible relations between the abundances of zinc and the light elements sodium, magnesium, and potassium in the atmospheres ofred giant branch (RGB) stars of the Ga…
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…
