| 研究実績の概要 |
During the second year of my fellowship, I have continued the work to understand the structure of the inner core and the inner core boundary region. The Earth’s inner core is the solid part of the Earth’s core, and is growing as the liquid part is freezing, because of the decrease of temperature in the center of the Earth. The flow inside the solid inner core is not yet fully understood. Seismic observations of the inner core have detected complex structures on several scales. During my Ph.D., I developed geodynamical models for deformation in the inner core. During this year, I developed a software to compare seismic observations and geodynamical models. This code propagates seismic rays in the geodynamical models, and allow easy comparisons.
