Kepler Mission Exoplanet Transit Observations

Kepler space telescope data contains observations of stellar brightness dips indicating potential exoplanet transits. The dataset is derived from NASA's Kepler mission, which operated from 2009 to 2018. It is a key resource for cataloging planets outside our solar system.

Use Cases

• Identify exoplanet candidates by detecting periodic dips in stellar flux time-series data.
• Classify planet types by modeling relationships between transit depth, duration, and orbital period.
• Predict stellar parameters like radius and effective temperature using observed transit light curves.
• Analyze false positive rates by comparing centroid motion data with transit signals.

Strengths

• Originates from NASA's Kepler mission, a dedicated space observatory for exoplanet discovery.
• Contains photometric data for over 150,000 stars monitored for four years.

Limitations

• Data is limited to a single field of view in the Cygnus-Lyra region, introducing observational bias.
• Confirmed exoplanet labels are a small subset of all observed transit events.
