The primordial abundance of 7Li as predicted by Big Bang Nucleosynthesis (BBN) is about a factor 3 larger than what has been observed in metal-poor halo stars. We analyze the possibility that this discrepancy originates from incorrect assumptions about the nuclear reaction cross sections relevant for BBN.

The ratio of the reaction rates of the competing channels 17O(a,g)21Ne and
17O(a ,n)20Ne determines the efficiency of 16O as a neutron poison in the
s process in low metallicity rotating stars. It has a large impact on the
element production, either producing elements to the mass range of A=90 in
case of a significant poisoning effect or extending the mass range up to
the region of A=150...

The 14N(p,gamma)15O reaction determines the rate of the CNO
cycle because it's the slowest nuclear reaction of the cycle. For a precise
cross section extrapolation to low energies one needs accurate knowledge
of the excitation function over a wide range of energy. Therefore the non-resonant cross section of 14N(p,gamma)15O was studied at beam energies of 0.5 - 1.5,MeV at the 3,MV Tandetron...

I will discuss recent measurements of neutron stars masses and radii and their implications for the equation of state of high density matter. I will focus in particular on the possible appearance of delta resonances, hyperons and strange quark matter and the dynamics of the formation process of such "exotic" degrees of freedom. Finally, I will present neutrino diffusion simulations of the...

The high-density nuclear equation of state within the Brueckner-Hartree-Fock many-body approach is discussed. Particular attention is paid to the effects of nucleonic three-body forces, the presence of hyperons, and the joining with an eventual quark matter phase.
The resulting properties of neutron stars, in particular the mass-radius relation, are determined and compared with recent...
