The Ba overabundance detected in the SN 1987A ejecta (Williams, 1987; Danziger et al., 1988) is intepreted in terms of slow-neutron-capture nucleosynthesis during core He burning in the (presumed) progenitor Sk-69 deg 202. The results of nucleosynthesis computations are reported, and their relevance to the observations is discussed. 24 references.
