Fusa Miyake is a cosmic ray physicist at Nagoya University, Japan, whose work measuring isotope abundances led to recognition of so-called Miyake events. These have resulted in reconciling differences between dates from documents and materials such as ice-cores and tree rings.
Fusa Miyake gained her doctorate from Nagoya University in 2013 and was then appointed as an assistant professor. In 2017 she was promoted to associate professor in the Division for Cosmic Ray Research within the Space-Earth Environmental Research Division.[1]
Her doctoral research identified events in the wood of long-lived Japanese cedar trees, now called Miyake events, where there are sudden increases in cosmogenic isotopes such as radioactive carbonisotope14 C, 10 Be and 36 Cl produced by cosmic rays originating from the Sun when large solar flares or eruptions occur. Although the event was initially proposed to be a signature of an unidentified supernova,[2] it was soon independently confirmed and proven to be the discovery of an extreme solar particle event.[3][4] The measurements utilised the 14 C polymer cellulose extracted from tree-rings formed in individual years that could be measured using accelerator mass spectrometry.[2][5] Detection of these isotopes in materials such as tree-rings and ice cores. Measuring these isotopes in materials that have been independently dated allow the events to be dated with precision. This gives information about the Sun's long-term activity. She identified an event in 775 during her doctoral work,[6] and along with colleagues, has subsequently identified events centred on 993-4[7] and also 660 and 5480 BCE.[8] By 2023, 6 Miyake events had been identified.[5]
Her subsequent research with worldwide collaborators, and that of other researchers, has suggested that the source of the radiation causing Miyake events is more complicated than from single solar events. Some may be from multiple solar flares, influenced by tree physiology or by interactions of high energy particles with the Earth's magnetic field.[5]
