(Oxford University Press, 2014-01)The aim of this paper is to quantify the amplitude of the predicted plateau in [α/Fe] ratios associated with the most metal-poor stars of a galaxy. We assume that the initial mass function (IMF) in galaxies is steeper ...

(IOP Publishing Limited, 2011-12-20)We report the discovery of eight lithium-rich field giants found in a high-resolution spectroscopic sample of over 700 metal-poor stars ([Fe/H] < −0.5) selected from the Radial Velocity Experiment survey. The ...

NLTE AND LTE Lick indices for red giants from [Fe/H] 0.0 TO −6.0 AT SDSS AND IDS spectral resolution (American Astronomical Society, 2015-09-01)We investigate the dependence of the complete system of 22 Lick indices on overall metallicity scaled from solar abundances, [M/H], from the solar value, 0.0, down to the extremely metal-poor (XMP) value of −6.0, for ...
