Carina OB1 Association X-Ray Point Source Catalog from XMM-Newton

235 X-ray point sources detected within the Carina OB1 stellar association by the XMM-Newton observatory. The catalog provides X-ray count rates in three energy bands and variability status for 557 detections, with cross-identifications to optical and infrared catalogs. This table was created by NASA's HEASARC in April 2008 based on source files from CDS Catalog J/A+A/477/593.

Use Cases

• Study X-ray formation mechanisms in stellar winds based on spectral characteristics of early-type stars.
• Identify and analyze pre-main sequence stars based on detected short-term X-ray variability.
• Cross-match X-ray sources with optical and infrared catalogs for multi-wavelength object identification.
• Investigate potential background Active Galactic Nuclei (AGNs) among the detected point sources.

Strengths

• Catalog contains 235 distinct X-ray point sources with 557 individual detections.
• Includes cross-identifications with optical and infrared catalogs, enabling multi-wavelength analysis.
• Data is derived from five observations with the XMM-Newton space observatory, a major scientific instrument.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the catalog table is unknown, which may limit suitability assessment.
• Last updated 2026-03-13 19:37:35.380437; freshness should be verified as the underlying observations are older.
