An international team of researchers working at a research site situated a mile and a half below China's Jinping Mountains, has found via experimentation, a likely explanation for the high concentrations of calcium seen in the oldest known star. The group describes their experiments in the journal Nature. Marco Pignatari and Athanasios Psaltis, with the University of Hull and the Technical University of Darmstadt, respectively, have published a News and Views piece outlining the work done by the team in the same journal issue.
