The effect of starspots on the ages of low-mass stars determined from the lithium depletion boundary
R. J. Jackson, R. D. Jeffries
In a coeval group of low-mass stars, the luminosity of the sharp transition between stars that retain their initial lithium and those at slightly higher masses in which Li has been…
Gaia-ESO Survey: The analysis of high-resolution UVES spectra of FGK-type stars
R. Smiljanic, A. J. Korn, M. Bergemann +99
The Gaia-ESO Survey is obtaining high-quality spectroscopic data for about 10^5 stars using FLAMES at the VLT. UVES high-resolution spectra are being collected for about 5000 FGK-t…
Empirical classification of VLT/Giraffe stellar spectra in the wavelength range 6440-6810 A in the gamma Vel cluster, and calibration of spectral indices
F. Damiani, L. Prisinzano, G. Micela +23
We study spectral diagnostics available from optical spectra with R=17000 obtained with the VLT/Giraffe HR15n setup, using observations from the Gaia-ESO Survey, on the gamma Vel y…
The effect of starspots on the radii of low-mass pre-main sequence stars
R. J. Jackson, R. D. Jeffries
A polytropic model is used to investigate the effects of dark photospheric spots on the evolution and radii of magnetically active, low-mass (M<0.5Msun), pre-main sequence (PMS) st…
The Gaia-ESO Survey: the Galactic Thick to Thin Disc transition
A. Recio-Blanco, P. de Laverny, G. Kordopatis +36
(Abridged) We have used the atmospheric parameters, [alpha/Fe] abundances and radial velocities, determined from the Gaia-ESO Survey GIRAFFE spectra of FGK-type stars (iDR1), to pr…
The Gaia-ESO Survey: Properties of the intermediate age open cluster NGC 4815
E. D. Friel, P. Donati, A. Bragaglia +34
NGC 4815 is a populous ~500 Myr open cluster at a Galactocentric radius of 7 kpc observed in the first six months of the Gaia-ESO Survey. Located in the inner Galactic disk, NGC 48…
