研究実績の概要

With Ph.D. student Irene Bonati, we finished development of the simulation codes, and we began to run models of inner core crystallization and potential for re-melting. This was included as a chapter in the dissertation of Dr. Bonati (graduated in March 2021), and is being formatted for journal submission. Another paper, regarding the subject of partial melting and instability of the inner core is also under preparation. I am now incorporating the latest mineral physics constraints on the Fe-H system, in collaboration with Professor Kei Hirose and his former student Dr. Sho Tagawa (we currently have a collaboration paper in press with Nature Communications). We did not have an opportunity to present our new results at a conference this year, owing to travel restrictions related to the COVID-19 pandemic.

現在までの達成度 (区分)

2: おおむね順調に進展している

理由

Although the COVID-19 pandemic presented some challenges, the project is moving forward with the engagement of a very good student. I am looking forward to publishing many interesting results in this coming year.

今後の研究の推進方策

I am ready to begin running calculations on the partial melting instability of the inner core. I already finished the linear stability analysis, and this is the last phase of the project according to the original plan.

次年度使用額が生じた理由

Computing fees, equipment, and data storage. Travel to a conference if possible.
