Exoplanet Discovery Catalog
Transit photometry candidates detected via BLS periodogram analysis of NASA TESS light curves with MCMC orbital parameter fitting
What is the Earth Similarity Index?
The Earth Similarity Index (ESI) quantifies the degree of similarity between a detected exoplanet candidate and Earth, incorporating planetary radius, equilibrium temperature, and orbital parameters. An ESI of 1.0 represents an exact Earth analog. Values exceeding 0.8 indicate strongly Earth-like characteristics consistent with conditions potentially favorable for liquid surface water.
Candidate Catalog
Candidate Validation Protocol
All candidates in this catalog have passed a multi-stage validation pipeline: Box Least Squares periodogram detection with SNR threshold filtering, Markov Chain Monte Carlo parameter estimation, stellar variability detrending, secondary eclipse analysis, odd-even transit depth comparison, and noise artifact rejection. Candidates are designated unconfirmed pending radial velocity follow-up observations.
Biosignature indicators are derived from atmospheric forward-modeling and represent preliminary spectroscopic signatures consistent with disequilibrium chemistry. These are statistical indicators, not confirmed detections of biological activity.
