Major achievements
Dr. Toriumi is a world leader in the study of the Sun’s magnetic structure and explosive mass ejections, utilizing both numerical simulations and the analysis of observational data. Through a series of comprehensive simulations, spanning from the deep convection zone to the surface layers, he elucidated the conditions under which delta-type sunspots, the source regions of massive solar flares, are formed, producing a number of outstanding results. Concurrently, by making extensive use of satellite observation data, he clarified the role of magnetic reconnection in energy release and jet formation around sunspots, thereby advancing our understanding of solar explosive phenomena. The series of research has earned high acclaim, culminating in an invited review article in a leading journal in solar physics. In recent years, he has also studied the properties of X-ray and ultraviolet radiation from solar-type stars, assessing their potential impacts on planetary environments. He is also playing a central role in the science planning for the upcoming solar observation mission SOLAR-C. His leadership across a wide range of activities—including the formulation of scientific objectives, the design of observational instruments, and the coordination of international collaborative research—is essential to the mission’s success.
