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…
The Gaia-ESO Survey: Chromospheric Emission, Accretion Properties, and Rotation in Velorum and Chamaeleon I
A. Frasca, K. Biazzo, A. C. Lanzafame +33
We use the fundamental parameters delivered by the GES consortium in the first internal data release to select the members of Vel and Cha I among the UVES and GIRAFFE spectrosc…
The Gaia-ESO Survey: CNO abundances in the open clusters Trumpler 20, NGC 4815, and NGC 6705
G. Tautvaišienė, A. Drazdauskas, Š. Mikolaitis +30
Aim of this work is to determine C, N, and O abundances in stars of Galactic open clusters of the Gaia-ESO survey and to compare the observed abundances with those predicted by cur…
The role of turbulent pressure as a coherent pulsational driving mechanism: the case of the delta Scuti star HD 187547
V. Antoci, M. Cunha, G. Houdek +6
HD 187547 was the first candidate that led to the suggestion that solar-like oscillations are present in delta Scuti stars. Longer observations, however, show that the modes interp…
Astrophysical Constraints on the Bumblebee Model
Jorge Páramos, Gonçalo Guiomar
In this work the Bumblebee model for spontaneous Lorentz symmetry breaking is considered in the context of spherically symmetric astrophysical bodies. A discussion of the modified…
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…
