A view of the Galactic halo using beryllium as a time scale
Rodolfo Smiljanic, L. Pasquini, P. Bonifacio +4
Beryllium stellar abundances were suggested to be a good tracer of time in the early Galaxy. In an investigation of its use as a cosmochronometer, using a large sample of local hal…
CCH in prestellar cores
M. Padovani, C. M. Walmsley, M. Tafalla +2
We study the abundance of CCH in prestellar cores both because of its role in the chemistry and because it is a potential probe of the magnetic field. We also consider the non-LTE…
Beryllium abundances and star formation in the halo and in the thick disk
R. Smiljanic, L. Pasquini, P. Bonifacio +4
[abridged] Beryllium is a pure product of cosmic ray spallation. This implies a relatively simple evolution in time of the beryllium abundance and suggests its use as a time-like o…
