Superbubbles and the Galactic evolution of Li, Be and B
Etienne Parizot
From a recent re-analysis of the available data, Be and B Galactic evolution appears to show evidence for a two-slope behaviour with respect to O. The inferred Be/O abundance ratio…

Bimodal production of Be and B in the early Galaxy
E. Parizot, L. Drury
Recently models based on the acceleration of metal-rich material inside superbubbles have been proposed to account for the observed abundances of Be and B in metal-poor halo stars.…

The superbubble model for Li, Be and B production and Galactic evolution
Etienne Parizot, Luke Drury
We show that the available constraints relating to LiBeB Galactic evolution can be accounted for by the so-called superbubble model, according to which particles are efficien…
