YSOVAR GGD 12-15: Infrared Time-Series Photometry of Young Stellar Objects

29,000 unique objects with mid-infrared light curves from the YSOVAR Spitzer Space Telescope program. The data provides time-series photometry at 3.6 and 4.5 microns for the Orion Nebula Cluster and 11 other star-forming cores. The project is led by NASA, with initial results published in 2011 and detailed conventions described in 2014.

Use Cases

• Analyze mid-infrared variability patterns of young stellar objects based on the time-series photometry.
• Model stellar accretion and disk processes based on light curve data from multiple star-forming regions.
• Compare stellar variability across different star-forming cores, including Orion, NGC 2264, and Serpens.
• Conduct statistical studies of young stellar object populations based on the ~29,000 unique objects.

Strengths

• Contains ~29,000 unique astronomical objects.
• Covers 12 distinct star-forming regions, including the Orion Nebula Cluster.
• Provides the first extensive mid-infrared time series for these targets.
• Data reduction and project conventions are documented in peer-reviewed publications.

Limitations

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