Major achievements

Futoshi Takahashi is developing original and advanced research rooted in advanced numerical simulation based on magnetohydrodynamics (MHD), observation and data analysis in wide fields of Earth and planetary electromagnetism, and sciences on Earth and planetary interiors. He challenged the MHD simulation of a low-viscosity fluid close to the Earth’s core, and in addition to reproducing the spatiotemporal characteristics of the geodynamo including magnetic field reversal, he developed for the first time a study approaching to the underlying physics. In collaboration with researchers of paleomagnetism and ultrahigh pressure experiments, he has conducted unique studies that constrain the material and thermal structure of the real deep Earth. In addition, he participated in lunar exploration by “Kaguya” and is currently involved in the Mercury exploration mission of “BepiColombo”, and is developing important and original research in wide fields and objects proposing a possibility that the Moon once had a dynamo with dipole magnetic field and true polar wandering, and a dynamo model to reproduce the peculiar magnetic field of Mercury, which is highly evaluated internationally.
