EXOVEIL – Single-Transit Exoplanet Detection via Stellar Behavior Learning

EXOVEIL is a Transformer-based exoplanet transit detection system that learns expected stellar brightness and flags deviations, enabling detection from a single transit event. It addresses a major gap in existing pipelines which require multiple transits. The system was trained on 16,499 Kepler light curves using self-supervised methods.

## EXOVEIL – Single-Transit Exoplanet Detection via Stellar Behavior Learning ### Overview EXOVEIL (arXiv:2606.02778, June 2025) is a transit detection system for identifying exoplanets from photometric light curves. Its distinguishing feature is the ability to detect planets that transit their host star **only once** in the observed data, a significant capability gap in existing detection pipelines. ### Architecture - A **Transformer world model** trained on 16,499 Kepler light curves using transit-masked self-supervised learning to predict expected stellar flux - A **matched-filter detector** with variance weighting to extract transit signals from prediction residuals - A **learned classifier** for transit candidate vetting ### Key Innovation Unlike existing systems that require phase-folded input (necessitating multiple observed transits for period estimation), EXOVEIL operates on raw flux time series. This makes it applicable to long-period planets — potentially including Earth-analog candidates — whose orbital periods exceed observational baselines. ### Scientific Context Single-transit detection is considered one of the hardest problems in exoplanet science. Long-period planets in the habitable zones of Sun-like stars transit infrequently; Kepler and TESS missions have accumulated single-transit candidates that existing automated pipelines cannot efficiently process. ### Strategic / IP Relevance - Novel application of Transformer world models to physical science problems - Self-supervised learning on domain-specific time series is a transferable technique - Potential for deployment in upcoming missions (PLATO, Roman Space Telescope) ### Connections Related to IceCube neutrino fingerprint work as part of the broader wave of physics-domain ML applications.
