An ancient extrasolar system with five sub-Earth-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-r…
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…
Revisiting the correlation between stellar activity and planetary surface gravity
P. Figueira, M. Oshagh, V. Zh. Adibekyan +1
Aims: We re-evaluate the correlation between planetary surface gravity and stellar host activity as measured by the index log(). This correlation, previously identified by…
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…
