IC 1396A and Trumpler 37 Chandra X-Ray Point Source Catalog

415 X-ray sources were identified from two Chandra-ACIS observations of the IC 1396A region, taken in March and June 2010. The catalog combines X-ray data with optical and infrared surveys to identify over 250 young stars, doubling the previously known population. The dataset was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Study triggered star formation based on the spatio-temporal gradient of stars identified towards HD 206267.
• Identify young stellar objects based on the combined X-ray, optical, and infrared source data.
• Analyze the population of extragalactic X-ray sources based on the catalog's separation of background and stellar sources.
• Investigate the structure of bright-rimmed clouds based on the spatial distribution of over 250 young stars in and around IC 1396A.

Strengths

• Contains 415 X-ray sources with quality filtering applied (sources with fewer than 3 total counts or a high probability of being a background fluctuation were omitted).
• Integrates data from multiple surveys, including Chandra X-ray observations and optical/infrared observations from FLWO and Calar Alto telescopes.
• Identifies over 250 young stars, which the description states doubles the previously known population in the region.

Limitations

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