Lupus 3 Star-Forming Region X-Ray Point Source Catalog

A 2007 catalog of 102 X-ray point sources detected in the Lupus 3 star-forming region by the XMM-Newton satellite's EPIC cameras during a ~22-kilosecond observation. The table, created by NASA's HEASARC, includes 25 sources with identified pre-main sequence stellar counterparts and X-ray luminosities ranging from 3e28 to 3e30 erg/s. The data originates from an analysis performed using the XMM-Newton Science Analysis Software (SAS).

Use Cases

• Identify and catalog young low-mass T Tauri stars based on their X-ray emission.
• Study the X-ray luminosity function of pre-main sequence stars in a star-forming region.
• Cross-match X-ray sources with optical and near-infrared catalogs to identify counterparts.
• Analyze the spatial distribution of X-ray sources within the Lupus 3 core region.

Strengths

• Contains 102 candidate X-ray sources detected with a likelihood threshold corresponding to 4.4 sigma.
• Provides X-ray luminosity data for 25 identified pre-main sequence stars.
• Data was processed using the standard source detection method in the XMM-Newton Science Analysis Software (SAS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a static catalog from a 2007 analysis; newer observations may exist.
