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…
Abundance ratios \& ages of stellar populations in HARPS-GTO sample
E. Delgado Mena, M. Tsantaki, V. Zh. Adibekyan +4
In this work we present chemical abundances of heavy elements (Z28) for a homogeneous sample of 1059 stars from HARPS planet search program. We also derive ages using parallaxes…
SWEET-Cat update and FASMA. A new minimization procedure for stellar parameters using high-quality spectra
D. T. Andreasen, S. G. Sousa, M. Tsantaki +6
Context: Thanks to the importance that the star-planet relation has to our understanding of the planet formation process, the precise determination of stellar parameters for the ev…
Searching for Li-rich giants in a sample of 12 open clusters: Li enhancement in two stars with substellar companions
E. Delgado Mena, M. Tsantaki, S. G. Sousa +6
The aim of this work is to search for Li-rich giants in a sample of clusters where planets have been searched, thus we can study the planet engulfment scenario to explain Li replen…
The Gaia-ESO Survey: Detailed Abundances in the Metal-poor Globular Cluster NGC 4372
I. San Roman, C. Muñoz, D. Geisler +28
We present the abundance analysis for a sample of 7 red giant branch stars in the metal-poor globular cluster NGC 4372 based on UVES spectra acquired as part of the Gaia-ESO Survey…
Correcting the spectroscopic surface gravity using transits and asteroseismology. No significant effect on temperatures or metallicities with ARES+MOOG in LTE
A. Mortier, S. G. Sousa, V. Zh. Adibekyan +2
Precise stellar parameters are crucial for several reasons, amongst which are the precise characterization of orbiting exoplanets and the correct determination of galactic chemical…
