The [alpha/Fe] ratios of very metal-poor stars within the integrated galactic initial mass function theory

Recchi, S.; Calura, F.; Gibson, Brad K.; Kroupa, P. (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 ...
Metal-poor lithium-rich giants in the radial velocity experiment survey

Ruchti, Gregory R.; Fulbright, Jon P.; Wyse, Rosemary F. G.; Gilmore, Gerard F.; Grebel, Eva K.; Bienayme, Olivier; Bland-Hawthorn, Joss; Freeman, Ken C.; Gibson, Brad K.; Munari, Ulisse (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

Short, C. Ian (Christopher Ian), 1965-; Young, Mitchell E.; Layden, Nicholas (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 ...
