Searching for the metal-weak thick disc in the solar neighbourhood
Bacham E. Reddy, David L. Lambert
An abundance analysis is presented of 60 metal-poor stars drawn from catalogues of nearby stars provided by Ariyanto et al. (2005) and Schuster et al. (2006). In an attempt to isol…
Heavy element abundances in giant stars of the globular clusters M4 and M5
David Yong, Amanda I. Karakas, David L. Lambert +2
We present a comprehensive abundance analysis of 27 heavy elements in bright giant stars of the globular clusters M4 and M5 based on high resolution, high signal-to-noise ratio spe…
Ultraviolet Survey of CO and H_2 in Diffuse Molecular Clouds: The Reflection of Two Photochemistry Regimes in Abundance Relationships
Y. Sheffer, M. Rogers, S. R. Federman +4
(Abridged) We carried out a comprehensive far-ultraviolet (UV) survey of ^12CO and H_2 column densities along diffuse molecular Galactic sight lines in order to explore in detail t…
Center-to-Limb Variation of Solar 3-D Hydrodynamical Simulations
L. Koesterke, C. Allende Prieto, D. L. Lambert
We examine closely the solar Center-to-Limb variation of continua and lines and compare observations with predictions from both a 3-D hydrodynamic simulation of the solar surface (…
Could the Ultra Metal-poor Stars be Chemically Peculiar and Not Related to the First Stars?
K. A. Venn, D. L. Lambert
Chemically peculiar stars define a class of stars that show unusual elemental abundances due to stellar photospheric effects and not due to natal variations. In this paper, we comp…
