| Outline of Final Research Achievements |
We have theoretically studied the role of magnetic fields in the early stages of the formation of stars such as the Sun. Stars are born in molecular clouds, which are composed mainly of molecular hydrogen gas. Most molecular clouds have an elongated filamentary structure, and a magnetic field penetrates perpendicular to their axis. We investigated the self-gravitational instability of long and thin molecular clouds penetrated by magnetic fields. We found that such a structure splits into several gas clumps regardless of the strength of the magnetic field. In addition, when the magnetic field is weak or there is magnetic diffusion, the central part of the gas clumps contracts and stars are formed. We also discuss the scenario from the formation of such filamentary molecular clouds to the star formation.
