In a previous work [1], given a putative vortex, it was determined whether itis non abelian or not by studying its radiation channels. The exampleconsidered there was a $SU(2)$ gauge model whose internal orientational modesare described by an sphere $S^2$. The non abelian effects presented in thisreference were not very pronounced, due to the compactness of this space. Inthe present work, this analysis is extended for a vortex whose internal spaceis non compact. This situation may be realised by semi-local supersymmetricvortices [2]-[9]. As the internal space has infinite volume, a largelyenergetic perturbation may propagate along the object. A specific configurationis presented, when the internal space is the resolved conifold with its Ricciflat metric. The curious feature about it is that it corresponds to a staticvortex, that is, the perturbation is only due to the internal modes. Even beingstatic, the emission of gravitational radiation is in the present case ofconsiderable order. This suggest that the presence of slowly moving objectsthat can emit a large amount of gravitational radiation is a hint of nonabelianity.
