Hungry Giants: WISE Excesses and Lithium Study of 316 K Giants

NASA assembled a catalog of 316 K-giant star targets to test the association between infrared excesses and lithium abundances. Two-thirds of the targets are thought to be lithium-rich. The multiwavelength catalog spans optical through 100 um data, incorporating data from SDSS, 2MASS, WISE, IRAS, and other surveys.

Use Cases

• Correlating infrared excesses with lithium abundances based on the multiwavelength catalog.
• Studying stellar evolution in K giants based on the assembled sample of lithium-rich stars.
• Analyzing multiwavelength photometric data from optical to far-infrared surveys.
• Investigating selection biases in stellar population studies based on the description of source assemblies.

Strengths

• Includes 316 specifically targeted K-giant stars.
• Assembles a multiwavelength catalog from 9 major astronomical surveys.
• Focuses on a sample where two-thirds of targets are thought to be lithium-rich.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect source selection bias inherent to the original studies (dlR97, C12, literature).
