Non-universal scalar-tensor theories and big bang nucleosynthesis
Alain Coc, Keith A. Olive, Jean-Philippe Uzan +1
We investigate the constraints that can be set from big-bang nucleosynthesis on two classes of models: extended quintessence and scalar-tensor theories of gravity in which the equi…
Cosmic Ray production of Beryllium and Boron at high redshift
Emmanuel Rollinde, David Maurin, Elisabeth Vangioni +2
Recently, new observations of Li6 in Pop II stars of the galactic halo have shown a surprisingly high abundance of this isotope, about a thousand times higher than its predicted pr…
Coupled Variations of Fundamental Couplings and Primordial Nucleosynthesis
Alain Coc, Nelson J. Nunes, Keith A. Olive +2
The effect of variations of the fundamental nuclear parameters on big-bang nucleosynthesis are modeled and discussed in detail taking into account the interrelations between the fu…
Population III Generated Cosmic Rays and the Production of Li6
Emmanuel Rollinde, Elisabeth Vangioni, Keith A. Olive
We calculate the evolution of Li6 generated from cosmic rays produced by an early population of massive stars. The computation is performed in the framework of hierarchical structu…
Gravitational Waves from the First Stars
Pearl Sandick, Keith A. Olive, Frederic Daigne +1
We consider the stochastic background of gravitational waves produced by an early generation of Population III stars coupled with a normal mode of star formation at lower redshift.…
Big bang nucleosynthesis constraints on scalar-tensor theories of gravity
Alain Coc, Keith A. Olive, Jean-Philippe Uzan +1
We investigate BBN in scalar-tensor theories of gravity with arbitrary matter couplings and self-interaction potentials. We first consider the case of a massless dilaton with a qua…
