This section will cover the nucleosynthesis in massive stars during their
evolution up to the supernova phase including the elements ejected through
stellar winds in the Wolf-Rayet phase. This will be followed by a review on
the theoretical results for the supernova yields and a discussion of the
uncertainties affecting these yields. The evolution and the nucleosynthesis
in intermediate stars will then be discussed as well as those stars'
contribution to the chemical enrichment of the ISM.

Section II:
Chemical Composition of Metal-Poor
Stars
Abundance analyses results will be reviewed, covering very metal-poor and
mildly metal-poor field stars as well as globular cluster stars. The
emphasis will be on the main differences and the common features.
1. Light element abundances in very metal-poor stars

2. Heavy element abundances in very metal-poor stars

3. Mildly metal-poor stars

4. Globular clusters
C. Sneden, Austin
Section III:
Metal-Poor Components of our
Galaxy
This section will cover what can be said as to the kinematics of metal-poor
stars and globular clusters. Formation scenarios of the thick disk and the
halo will be discussed.

2. Formation scenarios
R. Wyse, John Hopkins
Section IV:
HR Diagrams of Globular Clusters
This section will be a confrontation between observed colour-magnitude
diagrams and theoretical HR diagrams of globular clusters. Special emphasis
will be on the uncertainties affecting both the observational location of a
star in a colour-magnitude diagram and on the theoretical
uncertainties in the modelling of low mass stars used in the computation of
theoretical isochrones. Ages of globular clusters will also be addressed.
1. Photometry of globular cluster stars - CMDs

3. Ages of globular clusters

Section V:
Chemical and Dynamical Evolution of
Globular Clusters
Early stages of globular clusters will be presented with an emphasis on the
possibility of self-enrichment. It will be followed by a discussion on the
dynamical evolution of globular clusters with special attention given to the
conditions of disruption and to the evaporation of stars from a stable
cluster.
