| 研究開始時の研究の概要 |
The key question to be answered by this project is whether star formation at small spatial scales (0.1 parsec and smaller) in the Galactic Center and in the Galactic disk can be unified under the same theoretical framework. If the answer is yes, it will suggest an expansion of our current star formation models to more extreme environments. If the answer is no, it will suggest environment-dependent star formation models, and urge us to re-consider star formation in other extreme environments such as around active galactic nuclei.

| 研究実績の概要 |
In FY2020-2021, before I abolished the project on September 31st, I have been working on ALMA data to analyze a protoplanetary disk candidate in the Central Molecular Zone around the Galactic Center. The paper has been submitted and referees' feedback has been received. The updated draft is expected to be resubmitted by the end of the year. I joint an astrochemical study of the Sgr B2 region in the Central Molecular Zone, and detected a new organic molecule using ALMA archival data. I was the third author of the paper published by ApJ, and the result is highlighted on the ALMA-J website.
I submitted two ALMA Cycle 8 proposals related to the current research topic, and got one Grade A and one Grade B. I will use them to study magnetic field and chemistry in the Central Molecular Zone.
