Lithium isotopic abundances in metal-poor halo stars
Martin Asplund, David L. Lambert, Poul Erik Nissen +2
Very high-quality spectra of 24 metal-poor halo dwarfs and subgiants have been acquired with ESO's VLT/UVES for the purpose of determining Li isotopic abundances. The derived 1D, n…

Abundances in giant stars of the globular cluster NGC 6752
David Yong, Frank Grundahl, Poul Erik Nissen +2
Recent theoretical yields and chemical evolution models demonstrate that intermediate-mass AGB stars cannot reproduce the observed abundance distributions of O, Na, Mg, and Al. As…
