Osmium solar abundance

In addition to the rather astounding variation of huge lanthanide concentrations over time intervals of decades, HR 465 (RE-max) also shows [36] an enormous amount of tellurium, and, what is of interest in Sect. 4, also large abundances of palladium, osmium, platinum and mercury. The logio(Z/H)- -12 are 6.4 for Pd, above 8.0 for Te, below 3.0 for Ba, 5.3 for Os, 5.8 for Pt and 5.1 for Hg. This corresponds (with the solar values [1] given by Trimble) to overabundances D(Z) = 5.1 for Pd, probably above 6 for Te, below 1.0 for Ba, but 4.5 for Os, 3.7 for Pt and about 3 for Hg. It is perhaps even more impressive to transform the results [36] to weight concentrations in g/t, yielding 200 g palladium, more than 10 kg tellurium, less than 0.1 g barium, 30 g osmium, 90 g platinum, and 15 g mercury. These measurements were related to the r-process... [Pg.207]
