Tycho Double Star Catalog

The Tycho Double Star Catalog is a stellar catalog created by the Tycho Double Star project, which aimed to compile information about double stars in the Milky Way galaxy.

The Tycho Double Star Catalog contains information on approximately 2.5 million double stars.

The catalog includes data such as position, proper motion, brightness, and color index for each double star entry.

The catalog provides valuable information for studying the dynamics and distribution of double stars in our galaxy, which can help advance our understanding of stellar evolution and galactic structure.

The catalog was compiled from a combination of ground-based observations and data obtained by the Hipparcos satellite.

Yes, the Tycho Double Star Catalog is freely available to astronomers and researchers around the world for scientific purposes.

Yes, researchers can utilize the catalog's data and incorporate it into their scientific studies or analyses.

While efforts have been made to ensure accuracy, some entries in the Tycho Double Star Catalog may have uncertainties or errors due to various factors, such as observational limitations or data processing techniques.

For any further inquiries, you can reach out to the organization responsible for maintaining the catalog or consult relevant scientific literature on the subject.

The Tycho Double Star Catalog is not actively maintained or updated since it is based on historic observations spanning a specific period. However, other more recent catalogs may contain more up-to-date data on double stars.
