NGC 6334 Chandra X-Ray Point Source Catalog of 1607 Stellar Objects

1607 faint X-ray sources cataloged from Chandra Observatory images of the NGC 6334 star-forming region. The catalog provides arcsecond positions and line-of-sight absorption estimates, with about 95% of sources expected to be cluster members, primarily lower-mass pre-main-sequence stars. This table was created by NASA's HEASARC in August 2009 based on published astronomical research.

Use Cases

• Mapping spatial distribution of star clusters based on the ~10 distinct clusters identified in the X-ray images.
• Studying stellar evolution and demographics based on the estimated total population of 20,000-30,000 pre-main-sequence stars.
• Identifying heavily obscured stellar objects associated with known far-infrared sources and radio H II regions.
• Analyzing star formation history over millions of years based on the dispersion of dozens of likely OB stars.

Strengths

• Contains 1607 X-ray sources with precise arcsecond positions.
• Sources are analyzed using sensitive data analysis methods from Chandra Observatory images.
• Catalog identifies ~10 distinct star clusters and dozens of likely OB stars.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known (1607), but the underlying sample size for population estimates is extrapolated.
• Data last updated 2026-03-13; freshness should be verified for current research.
