New EncoTESS model efficiently analyzes stellar light curves for age prediction

By PulseAugur Editorial · [1 sources] ·

Researchers have developed EncoTESS, a novel Time Series Foundation Model (TSFM) designed to analyze raw TESS light curve data from stars. This model is significantly smaller than typical TSFMs, making it accessible for use on standard laptops. EncoTESS effectively handles common issues in TESS data such as noise, irregular sampling, and data gaps, encoding light curves into a latent space for inferring stellar properties. It demonstrates particular effectiveness in predicting stellar age, outperforming existing methods for younger stars. AI

IMPACT This model could accelerate astrophysical research by providing a more efficient tool for analyzing stellar data and inferring properties like age.

    EncoTESS: Age-Sensitive Encodings from Raw TESS Light Curves

    arXiv:2608.25019v1 Announce Type: cross Abstract: Main sequence stars of spectral types late F through M exhibit systematic variability in photometric light curves, particularly when they are young. Rotational modulation of starspots manifests as quasi-sinusoidal variability, whi…
