In a study led by former postdoctoral scholar Levke Kööp, Associate Professor (Part-time) Phlipp Heck, Professor Andrew Davis, graduate student Jennika Greer, and colleagues at the Swiss Federal Institute of Technology (ETH) in Zurich have used the concentrations of helium and neon isotopes in little blue crystals of the mineral hibonite to show that the Sun was much more active in its early history than it is today. Their work, recently published in Nature Astronomy, attracted the attention of several news outlets, including the New York Times.
