Catalog of 760 Galactic O-Type Stars with Spectral and Photometric Data

A galactic catalog of 760 O-type stars compiled from literature sources. The table is based on the Catalog of Galactic O-Type Stars (Garmany, Conti, and Chiosi 1982) and includes designations, spectral types, UBV photometry, cluster memberships, positions, and source references. NASA HEASARC provided the service, updating positions via SIMBAD and removing or modifying erroneous entries.

Use Cases

• Analyzing the distribution and properties of massive O-type stars based on spectral types and luminosity classes.
• Studying stellar distances and absolute magnitudes based on derived values included in the catalog.
• Cross-referencing stellar identifications using provided designations like HD and DM numbers.
• Investigating cluster membership patterns for O-type stars within the Milky Way.

Strengths

• Contains 760 distinct stellar entries, providing a substantial sample of O-type stars.
• Includes derived values like absolute visual and bolometric magnitudes and distances.
• Positions were updated for accuracy using the SIMBAD database.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is based on literature compilations from the 1970s and early 1980s; newer observations are not included.
