Abstract

The spectra of low metallicity stars with large abundances of carbon and neutron-capture elements are discussed, with special emphasis on the blue metal-poor star CS9497-030, which has an extremely large abundance of lead. This object, like essentially all of its class, has obvious enhancements of the products of slow neutron-capture nucleosynthesis, probably delivered to it by a former asymptotic branch companion star. However, its neutron-capture abundance cannot be explained entirely in this fashion; significant prior contributions from rapid neutron-capture processes seem to be required.
