Li isotopes in metal-poor halo dwarfs, a more and more complicated story [PDF]

open access: yes, 2009
The nuclei of the lithium isotopes are fragile, easily destroyed, so that, at variance with most of the other elements, they cannot be formed in stars through steady hydrostatic nucleosynthesis.

Identification of Functional Cellular Markers Related to Human Health, Frailty and Chronological Age

open access: yesAging Cell, Volume 24, Issue 9, September 2025.
Human skin fibroblasts in vitro preserve the memory of age and health. ABSTRACT Aging leads to a decline in physiological reserves, an increase in age‐related diseases, reduced functional ability and a shortened healthspan. While molecular markers of chronological aging exist, their link to general health and intrinsic capacity (IC), a composite ...

Lithium in the Upper Centaurus Lupus and Lower Centaurus Crux Subgroups of Scorpius-Centaurus [PDF]

open access: yes, 2011
We utilize spectroscopically derived model atmosphere parameters and the \ion{Li}{1} $\lambda6104$ subordinate line and the $\lambda6708$ doublet to derive lithium abundances for 12 members of the Upper-Centaurus Lupus (UCL) and Lower-Centaurus Crux (LCC)
