Summary

Story summary

Uppsala University researchers found the Sun holds 55 % more silver than earlier estimates.
Lead author Sema Caliskan said this narrows the gap with CI chondrite meteorites to about 15 %.
The revision cuts the previous 78 % discrepancy between solar and meteoritic silver to within measurement uncertainties.
The team used a 3-D non-equilibrium solar model with UV effects on 57 energy levels and 183 silver transitions, computed on the Tetralith supercomputer.
