StarDB: analysis of spatial and temporal variability in astronomical data

This database provides variability analysis of astronomical data from various sources. We provide statistical analysis of spatial and temporal changes in astronomical objects. However, original light curves and other raw data are not provided in this database directly if we do not archive here. In general, each survey team has maintained its own database. In StarDB, we provide only links to the original database for individual objects, and in some cases plotting and extracting data from the original database.

This database also collects association of variability analysis with multi-wavelength data which mainly range from UV to IR. The current database uses GALEX for UV, SDSS for optical, and 2MASS for NIR, and IRAS/AKARI/WISE for IR wavelength ranges. Some analysis also uses Spitzer and X-ray data too. Future updates will include association results to most recent catalogs from other projects such as GALEX and SDSS. Although the database keeps information on what objects in other multi-wavelength data are matched, we do not store these multi-wavelength properties in the database. Simply, this web interface shows links to the original database of the multi-wavelength data.

We try to make the web interface compatible to the international standard of the Virtual Observatory. For example, cone search is supported with output in the VOtable format. When you have questions and suggestions about this web interface, please contact people who are relevant to your questions or suggestions. People are introduced in the people menu in the above.
