| Abstract: |
Small solar system bodies (SSSBs) can be found among many observed
astronomical objects. We need to construct an eļ¬cient method to extract and identify
the SSSBs among a huge number of detected sources observed with large telescopes
since SSSBs are moving objects. We use photometric and imaging data obtained with
the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) survey for the SSSB
extraction. In prototyping the system, we first constructed the PostgreSQL database of
photometric data of detected sources for all frames obtained with the HSC-SSP Wide
survey between March 2014 and January 2018. Next, we developed a system to effectively extract and identify known SSSBs from the sources registered to the database.
As the first result, we identified > 500,000 events for >100,000 SSSBs from the HSC-SSP data of 174 nights. The final goal of this project is to develop a system of fast
extraction and identification, using a hyper-speed database management system and a
large-scale parallel computing system, for known and newly discovered solar system
objects among the Subaru HSC data, and to make the HSC SSSB catalog. |
