C2D Full STARS Catalog: 160 Targeted Stars from Spitzer Legacy Program

The Cores to Disks (C2D) Spitzer Legacy Program observed about 150 known compact cores and surveyed five nearby large molecular clouds for candidate protostars. The Full STARS Catalog provides a list of 160 targeted stars, likely containing data from the IRAC, MIPS, and IRS instruments. This dataset was published by the National Aeronautics and Space Administration and was last updated on March 13, 2026.

Use Cases

• Identify candidate protostars and substellar objects based on infrared observations.
• Study the evolutionary sequence from molecular cores to protoplanetary disks based on the program's stated scope.
• Analyze the evolution of circumstellar dust in young systems with ages up to about 10 million years.
• Compare star-forming environments across a range of cloud masses and stellar masses.

Strengths

• Data originates from the Spitzer Space Telescope's three instruments (IRAC, MIPS, IRS), a major NASA observatory.
• Targets a specific evolutionary sequence with about 150 known cores and 160 targeted stars.
• Surveys five of the nearest large molecular clouds, providing a contextual spatial scope.

Limitations

• The description notes this is the 'most complete but least reliable' list of sources for the STARS fields.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and sample data are unavailable, which may limit suitability assessment.
