Extrasolar Planet Catalog from Professional Astronomy Surveys

The Extrasolar Planets Encyclopedia is a working tool compiling the latest exoplanet detections announced by professional astronomers. It is maintained by Jean Schneider and updated frequently, intended to facilitate quantitative research in exoplanetology. Stellar data such as positions, distances, magnitudes, mass, and metallicities are incorporated from sources like Simbad and professional papers.

Use Cases

• Analyze correlations between stellar metallicities and detected exoplanet properties to test formation theories.
• Calculate orbital parameters and physical characteristics from the latest announced detections for population studies.
• Track the temporal evolution of the catalog's entries, such as positions and distances, to monitor discovery trends.
• Integrate stellar data like V and other magnitudes with exoplanet data to model system architectures.

Strengths

• Compiles data from multiple major professional astronomy surveys, including the Anglo-Australian Planet Search and the Geneva Extrasolar Planet Search Programmes.
• Updated on a frequent basis as needed, with a last recorded update in March 2026.
• Includes detailed stellar parameters such as positions, distances, magnitudes, mass, and metallicities sourced from authoritative references.

Limitations

• The specific number of rows (exoplanet records) and columns (features) is not provided in the input, limiting precise assessment of scale.
• Data is announced by various professional teams, potentially introducing heterogeneity in measurement standards or reporting formats.
• Relies on external sources like Simbad for stellar data, which may have their own update cycles and accuracy constraints.
