The Tc trend in the Zetta Reticuli system: N spectra - N trends
V. Adibekyan, P. Figueira, E. Delgado Mena +4
It is suggested that the chemical abundance trend with the condensation temperature, Tc , can be a signature of rocky planet formation or accretion. Recently, a strong Tc trend was…
Precise masses for the transiting planetary system HD 106315 with HARPS
S. C. C. Barros, H. Gosselin, J. Lillo-Box +45
The multi-planetary system HD 106315 was recently found in K2 data . The planets have periods of and days, and radii of a…
Mg/Si mineralogical ratio of low-mass planet hosts. Correction for the NLTE effects
V. Adibekyan, H. M. Goncalves da Silva, S. G. Sousa N. C. Santos +2
Mg/Si and Fe/Si ratios are important parameters that control the composition of rocky planets. In this work we applied non-LTE correction to the Mg and Si abundances of stars with…
Chemical abundances of 1111 FGK stars from the HARPS GTO planet search program II: Cu, Zn, Sr, Y, Zr, Ba, Ce, Nd and Eu
E. Delgado Mena, M. Tsantaki, V. Zh. Adibekyan +4
To understand the formation and evolution of the different stellar populations within our Galaxy it is essential to combine detailed kinematical and chemical information for large…
CNO behaviour in planet-harbouring stars. I Nitrogen abundances in stars with planets
L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4
Carbon, nitrogen, and oxygen (CNO) are key elements in stellar formation and evolution, and their abundances should also have a significant impact on planetary formation and evolut…
The Gaia-ESO Survey: Inhibited extra mixing in two giants of the open cluster Trumpler 20?
R. Smiljanic, E. Franciosini, S. Randich +32
We report the discovery of two Li-rich giants, with A(Li) ~ 1.50, in an analysis of a sample of 40 giants of the open cluster Trumpler 20 (with turnoff mass ~ 1.8 Msun). The cluste…
