IC 348 Chandra X-Ray Point Source Catalog: 215 Detected Sources

A 53 ks Chandra X-Ray Observatory image of the young stellar cluster IC 348 detected 215 X-ray sources. The catalog, created by NASA HEASARC in January 2007, includes 115 identified cluster members, 58 likely new members, and X-ray emission from brown dwarfs and protostars. About 40 sources without optical/IR counterparts are likely extragalactic background objects.

Use Cases

• Identify new stellar cluster members based on X-ray emission.
• Study X-ray luminosity functions for stars with masses between ~0.15 and 2 solar masses.
• Analyze X-ray emission from brown dwarfs and candidate brown dwarfs.
• Investigate the population of extragalactic background X-ray sources in a cluster field.

Strengths

• Deep 53 ks observation with a sensitivity limit of ~1e28 ergs/s, more than 10 times deeper than previous ROSAT images.
• 215 X-ray sources detected, with optical/IR counterparts identified for most.
• X-ray emission detected from four of 13 known brown dwarfs and three of 12 brown dwarf candidates.

Limitations

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