| Outline of Annual Research Achievements |
Magnetic fields play an important role in the evolution of massive stars (those with initial masses above 8 solar masses). This project aims to combine numerical and observational results to further our understanding. I visited collaborators at the IAC, Spain. With collaborators from Japan, Germany and the US, we are submitting a paper to MNRAS. This includes the extension of magnetic stellar evolution models to low-metallicity environments. I disseminated research results at national and international conferences (EAYAM, ASJ Spring Annual Meeting, NAOJ Division of Science, Magnetic fields from clouds to stars: Bfields-2024). With collaborators in Austria and the US, we are further progressing with a population synthesis study.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The project is progressing.
|
| Strategy for Future Research Activity |
The project will continue as expected.
|
| Causes of Carryover |
I received other grants for travel. Therefore, I will roll-over the amount from last year.
