Fragmentation spectra of strange quark matter in a type-II supernova scenario

We present and discuss calculations of strange quark matter fragmentation expected in the ejection of matter by a type-II supernova in the proposed scenario where the collapse of the progenitor is driven by the nuclear matter quark matter conversion. Relevant issues such as the dynamical evolution of the ejecta and interactions with the outgoing stellar shells are addressed with the aim of understanding the mass distribution and spectra of strangelets at the sources.
