I summarize recent observational progress on measurement of the elemental
abundances of early generation stars, which have recorded
(and preserved) the first episodes of nucleosynthesis in the Galaxy.
I discuss two major recent surveys, one just completed, one just beginning.
The first, the Hamburg/ESO R-process-Enhanced Star (HERES) survey has
obtained ``snapshot'' high-resolution...

A variety of astrophysical processes contribute to the synthesis of heavier
elements in nature. The characteristics of the processes are governed by the
astrophysical environment and details of the nuclear processes involved.
Experiments performed at ISOLDE have played a central role in developing
understanding of these processes. In this presentation, highlights to be discussed...

The first evidence of the occurrence of nucleosynthesis in stars was provided in the
1950s by the detection of the unstable heavy element technetium in the atmospheres
of stars on the Asymptotic Giant Branch (AGB), a late evolutionary phase of stars of
low mass. Technetium can be produced by slow neutron captures (the s process) and
thus its detection requires that neutron source...

As pointed out by Willie Fowler, the goals of nuclear astrophysics are to understand
the mechanism of Nucleosynthesis and the process of energy generation in stellar
environments. While a good deal is now known on what occurs in quiescent stellar
burning, much less is known about pathways to heavy element production in explosive
scenario. The former is largely dominated by nuclear...

In the last decades considerable effort in experimental nuclear astrophysics, stellar
modelling, and observations led to an improved understanding of various
nucleosynthesis scenarios. This is particularly true for the main s process in
low-mass AGB stars, which is largely responsible for the production of about half of
the elemental abundances in the mass range 90 ≤ A ≤ 209. The weak s...

Important effort has been devoted in the last decades to measure reaction cross
sections. These measurements are fundamental to put the nuclear astrophysics models
on a sound basis. However, despite such effort, many nuclear applications, and most
particularly nuclear astrophysics, still require the use of theoretical predictions
to estimate experimentally unknown cross sections. Most...
