| Outline of Annual Research Achievements |
In Fiscal Year 2018 I started with the preparations for the project. I started some implementations of the proposed idea, but could not test them thoroughly yet. I am collaborating with colleagues (including outside the institution wherer I reside and outside of Japan) who are expert in magnetic properties of high-density matter and are providing useful help and suggestions for common research.
We have been performing our first accurate simulations of relativistic resistive magnetohydrodynamics for binary neutron star mergers. We have already observed and qualitatively analysed one of the strong instabilities expected to develop, the Kelvin-Helmholtz instability, which also produces a fast exponential growth of the magnetic field.We confirmed that its development can cause increases of the initial magnetic field of up to about three orders of magnitude.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
The project has been delayed because of lack of time due to additional duties imposed on me in the past fiscal year. Furthermore, I could not find a suitable doctoral student (research assistant) to help in the coding and testing. This is also why I did not spend all the funds allocated for the past fiscal year. In the current Fiscal Year I plan to hire such a research assistant and this will speed up progress.
|
| Strategy for Future Research Activity |
The plans for the research scheme will not be substantially changed. However, this fiscal year I will probably have more time to work on this project and progress will be faster. As mentioned above, I have good prospects to find a research assistant who may assist me in this project.
|
| Causes of Carryover |
In the previous fiscal year, I planned to buy a powerful laptop computer, but the remaining funds were not sufficient, therefore I am going to spend the remaining amount from the previous fiscal year this fiscal year for buying that laptop.
