The 7th star (HD 160617) shows the remarkable aspect of deficient B, probably deficient Be, and completely normal Li. No stellar destruc

System Safety in an IT Service Organizationhe beryllium and boron abundances in halo stars have been achieved by the 10 meter KECK telescope and the Hubble Space Telescope. These observations indicate a quasi linear correlation between Be and B vs Fe, at least at low metallicity, which, at first sight, is contradictory to a dominating GCR or

Sudipta Das,N. Anveshkumar,Arindam Biswas a turbulent diffusion process takes place. However, this model predicts a lithium abundance which is strongly rotation dependant, contrary to the observations. Furthermore, the diffusion coefficient being large all over the radiative zone, it prevents the possibility of gravitational separation by

In favour of D, the main arguments are the relative simplicity of the formation/destruction schema, but this is challenged by the large uncertainties on the choice of its actual
