YSOVAR NGC 1333: Mid-Infrared Light Curves of Young Stellar Objects

The YSOVAR program obtained the first extensive mid-infrared time series photometry of the Orion Nebula Cluster and 11 other star-forming cores using the Spitzer Space Telescope. It contains light curves for approximately 29,000 unique objects in the 3.6 and 4.5 micron IRAC channels. The data is from NASA, with initial results described in 2011 and project details published in 2014.

Use Cases

• Modeling stellar variability patterns based on mid-infrared time series photometry.
• Identifying and classifying young stellar objects based on their light curve behavior.
• Conducting comparative studies of stellar variability across different star-forming regions mentioned in the description.

Strengths

• Contains light curves for approximately 29,000 unique astronomical objects.
• Provides the first extensive mid-infrared time series photometry for the target regions.
• Data is from the Spitzer Space Telescope, a major NASA observatory.

Limitations

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