Exoplanets

When a planet passes in front of its host star, the resulting photometric dip — a transit light curve — encodes the planet's radius, orbital inclination, and the limb-darkening profile of the star. With enough precision, repeated transits also reveal atmospheric absorption signatures, orbital decay, and transit-timing variations caused by companion planets.

We develop ML-assisted pipelines for radial-velocity analysis and transit detrending that reduce sensitivity to stellar activity — the dominant noise source in exoplanet detection. Our 2026 paper introduced a vision-transformer model for radial-velocity analysis that improves planet recovery in low signal-to-noise regimes.
