Exoplanet hosts reveal lithium depletion: Results from a homogeneous statistical analysis
P. Figueira, J. P. Faria, E. Delgado-Mena +4
Aims. We study the impact of the presence of planets on the lithium abundance of host stars and evaluate the previous claim that planet hosts exhibit lithium depletion when compare…
Gaia-ESO Survey: The analysis of high-resolution UVES spectra of FGK-type stars
R. Smiljanic, A. J. Korn, M. Bergemann +99
The Gaia-ESO Survey is obtaining high-quality spectroscopic data for about 10^5 stars using FLAMES at the VLT. UVES high-resolution spectra are being collected for about 5000 FGK-t…
Spectroscopic parameters for solar-type stars with moderate/high rotation. New parameters for 10 planet-hosts
M. Tsantaki, S. G. Sousa, N. C. Santos +5
Planetary studies demand precise and accurate stellar parameters as input to infer the planetary properties. Different methods often provide different results that could lead to bi…
The Gaia-ESO Survey: metallicity of the Chamaeleon I star forming region
L. Spina, S. Randich, F. Palla +37
Context. Recent metallicity determinations in young open clusters and star-forming regions suggest that the latter may be characterized by a slightly lower metallicity than the Sun…
The Gaia-ESO Survey: the first abundance determination of the pre-main-sequence cluster Gamma Velorum
L. Spina, S. Randich, F. Palla +36
Knowledge of the abundance distribution of star forming regions and young clusters is critical to investigate a variety of issues, from triggered star formation and chemical enrich…
The HARPS search for southern extra-solar planets XXXV. The interesting case of HD41248: stellar activity, no planets?
N. C. Santos, A. Mortier, J. P. Faria +21
The search for planets orbiting metal-poor stars is of uttermost importance for our understanding of the planet formation models. However, no dedicated searches have been conducted…
