LMC 30 Doradus: Chandra X-Ray Point Source Catalog for a Star-Forming Complex

A 1999 September 21 Chandra Observatory observation of ~21 ks duration provides this catalog of X-ray point sources in the 30 Doradus star-forming region of the Large Magellanic Cloud. The table lists sources detected in a 17' x 17' field centered on the massive cluster R136, resolving it into almost 100 sources. This HEASARC table was created by NASA in February 2007 based on published research.

Use Cases

• Analyzing the correlation between X-ray luminosity and stellar properties like binarity and wind characteristics based on the observed scatter in Lx.
• Studying the X-ray point-source population within a massive star-forming region based on the catalog of detected sources.
• Comparing X-ray emission from Wolf-Rayet stars based on the detection of 20 out of 32 such stars in the field.
• Investigating the life cycle of massive stellar clusters through X-ray studies as mentioned in the description.

Strengths

• Data originates from the Chandra X-Ray Observatory, a high spatial-resolution instrument.
• Observation placed the target cluster R136 at the aim point for detailed analysis.
• Resolves the massive cluster R136 at the sub-arcsecond level into almost 100 X-ray sources.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The table includes lower-significance tentative sources which the authors note should not be considered definitive.
