Among their topics are experimental results on fractionation of the highly siderophile elements at variable pressures and temperatures during planetary and magmatic differentiation, nucleosynthetic isotope variations of siderophile and chalcophile elements in the solar system, the distribution and processing of highly siderophile elements in cratonic mantle lithosphere, chalcophile and siderophile elements in mantle rocks: trace elements controlled by trace minerals, petrogenesis of the platinum-group minerals, and highly siderophile and strongly chalcophile elements in magmatic ore deposits.
A naive conclusion to be drawn is that the observed luminosity-decline relationships suggest that a correlation exists between the strength and energetics produced by the central engine and the resultant nucleosynthetic yields of [sup.56]Ni.
