RCW 38 Chandra X-Ray Point Source Catalog: 536 Sources

A catalog of 536 X-ray sources identified in the high-mass star-forming region RCW 38 using Chandra data. The table results from a study combining Chandra X-ray, Spitzer IRAC, and 2MASS data to identify 624 young stellar objects and analyze subclustering. NASA HEASARC created this table in January 2012 based on the reference paper.

Use Cases

• Identify and classify young stellar objects based on X-ray and infrared data mentioned in the description
• Analyze spatial subclustering of stars within a massive star-forming region
• Study the gas-to-dust ratio in star-forming environments using X-ray derived hydrogen column density
• Investigate infrared variability among protostars and pre-main-sequence stars

Strengths

• Contains 536 identified X-ray sources from Chandra observations
• Study identifies 624 young stellar objects, including 23 class 0/I and 90 flat spectrum protostars
• Data combines multiple observational sources: Chandra X-ray, Spitzer IRAC, and 2MASS

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
