VLA Goulds Belt Survey: 610 Radio Sources in the Taurus-Auriga Star-Forming Complex

A catalog of 610 radio sources detected in the Taurus-Auriga star-forming complex using the Karl G. Jansky Very Large Array. The data includes 59 sources related to young stellar objects and 18 to field stars, with observations conducted at 4.5 GHz and 7.5 GHz across three periods in 2011. The study was published by researchers and the dataset is hosted by the National Aeronautics and Space Administration.

Use Cases

• Classifying radio emission mechanisms (thermal vs. non-thermal) based on source properties mentioned in the description.
• Correlating radio and X-ray observations of young stellar objects to study the Güdel-Benz relation.
• Identifying candidate young stellar objects from the list of 46 unidentified radio sources with compatible properties.
• Comparing radio properties of young stars across different evolutionary classes (I, II, III) and star-forming regions.
• Analyzing the spatial distribution of radio sources across 127 observed fields in the Taurus-Auriga complex.

Strengths

• Contains 610 detected radio sources with 59 identified as young stellar objects.
• Observations were made at high sensitivity, with noise levels as low as ~18 µJy at 7.5 GHz.
• Multi-epoch observations from three time periods in 2011 provide temporal data.
• Covers 127 target fields across the Taurus-Auriga complex, providing spatial coverage.

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 observational bias inherent to the specific target fields chosen to cover known young stellar objects.
