Project

A Robust Pipeline for TESS Eclipsing Binaries: Detrending, Period Validation, Eclipse Modeling, and Vetting

  • Optimized the STANLEY algorithm to analyze TESS photometry for a systematic, automated search for circumbinary planets (CBPs).
  • End-to-end framework including gap-aware preprocessing, harmonic removal with model selection, iterative BLS and period refinement, eclipse modeling, and astrophysical vetting of secondary eclipses.

MCMC Modeling

Posterior inference, trace diagnostics, best-fit overlays.

  • Bayesian parameter inference for light-curve models (priors, likelihood, posterior).
  • Multi-walker chains, burn-in, autocorrelation and trace-based convergence checks.
  • Trace plots, residual QA, and model overlays.

Eclipsing Binary Populations

Data generation and analysis from synthetic populations.

  • Statistical analysis of population synthesis across periods, eccentricities, and stellar radii.
  • Periods and eccentricities show low p-scores, indicating eclipsing binaries are not representative of the overall population.
  • Stellar radii yield higher p-scores, consistent with the overall population.
