Be Stars Catalog: 1,159 Non-Supergiant B-Type Stars with Balmer Emission

1,159 stars are included in this compilation of Be stars, defined as non-supergiant B-type stars that have shown emission in at least one Balmer line. The catalog was compiled by NASA HEASARC, excluding stars without published MK spectral types except for 132 stars from a specific 1973 study. It was last updated on March 13, 2026.

Use Cases

• Classifying Be stars based on the defined criteria of spectral type and Balmer line emission.
• Studying stellar populations and the prevalence of emission-line characteristics in B-type stars.
• Cross-referencing stellar data from the Bidelman and MacConnell (1973) study with other catalogs.
• Analyzing the distribution and properties of non-supergiant B stars that exhibit emission features.

Strengths

• Contains 1,159 stars, providing a substantial sample for analysis.
• Uses a clear, published definition for star inclusion (non-supergiant B star with Balmer emission).
• Compiled and maintained by NASA HEASARC, an authoritative source for astrophysics data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal or observational bias inherent to the source studies.
