IC 348 Chandra X-Ray Point Source Catalog 2: 290 Sources in a Young Stellar Cluster

NASA's Chandra X-ray Observatory catalog of 290 X-ray point sources in the IC 348 open cluster, a young (~2-3 million years) stellar group about 310 parsecs away. The data merges four Chandra observations to provide a deeper view, with 185 sources associated with known cluster members. The catalog includes fundamental stellar parameters, infrared excess, H-alpha emission, and mass accretion rates for studying stellar coronae.

Use Cases

• Analyzing X-ray luminosity functions based on stellar mass and evolutionary stage mentioned in the description
• Investigating correlations between X-ray emission and accretion/disk presence based on H-alpha and infrared excess data
• Comparing stellar coronal properties between low-mass and higher-mass stars using the provided stellar parameters
• Studying the universality of the Lx/Lbol ratio decline at the low-mass end by comparing with analogous samples like the Orion Nebula Cluster

Strengths

• Merges four Chandra observations for a deeper and more spatially complete X-ray view than previous studies
• Contains 290 X-ray sources, with 185 associated with known cluster members (~60% detection rate)
• Includes fundamental stellar parameters, infrared excess, H-alpha emission, and mass accretion rates for multi-wavelength analysis

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• X-ray flux upper limits for 129 observed but non-detected members are not included in this representation
