Brief Introduction of Research
- Majority of young stars form within embedded star clusters and their natal clouds show filamentary structures. These filamentary structures extend over parsec scales and often show hierarchical structures. This hierarchy suggests multi-scale fragmentation processes within the filaments that may play a central role in the star formation process. It is also suggested that longitudinal gas inflows along filaments may feed the dense cores and facilitate their growth, especially for the cores located in hubs at the junction of multiple filaments. The process of filament fragmentation and core formations is not yet well understood. My research interest is observationally studying spatial structures, physical conditions, and dynamics of the molecular filaments and embedded cores to reveal the initial condition of star formation and evolutionary processes at the earliest protostellar phase.
