CNO behaviour in planet-harbouring stars. II. Carbon abundances in stars with and without planets using the CH band
L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4
Context. Carbon, oxygen and nitrogen (CNO) are key elements in stellar formation and evolution, and their abundances should also have a significant impact on planetary formation an…
Gaia-ESO Survey: The analysis of pre-main sequence stellar spectra
A. C. Lanzafame, A. Frasca, F. Damiani +70
This paper describes the analysis of UVES and GIRAFFE spectra acquired by the Gaia-ESO Public Spectroscopic Survey in the fields of young clusters whose population includes pre-mai…
Solar analogs with and without planets: T trends and galactic evolution
V. Zh. Adibekyan, J. I. Gonzalez Hernandez, E. Delgado Mena +4
We explore a sample of 148 solar-like stars to search for a possible correlation between the slopes of the abundance trends versus condensation temperature (known as the Tc slope)…
Li abundances in F stars: planets, rotation and galactic evolution
E. Delgado Mena, S. Bertrán de Lis, V. Zh. Adibekyan +7
We find that hot jupiter host stars within the T range 5900-6300K show lower Li abundances, by 0.14 dex, than stars without detected planets. This offset has a signi…
Stars with and without planets: Where do they come from?
V. Zh. Adibekyan, J. I. Gonzalez Hernandez, E. Delgado Mena +5
A long and thorough investigation of chemical abundances of planet-hosting stars that lasted for more than a decade has finally beared fruit. We explore a sample of 148 solar-like…
On the origin of stars with and without planets. Tc trends and clues to Galactic evolution
V. Zh. Adibekyan, J. I. Gonzalez Hernandez, E. Delgado Mena +5
We explore a sample of 148 solar-like stars to search for a possible correlation between the slopes of the abundance trends versus condensation temperature (known as the Tc slope)…
