He Abundance of Dense Circumstellar Clumps in the Cassiopeia A Supernova Remnant
We report on the result of He abundance analysis of dense circumstellar clumps in the young supernova remnant Cassiopeia A. These clumps, which are called quasi-sta tionary flocculi (QSFs), are known from previous optical studies to be enriched in He along with N, but the degree of He overabundance...
