Overview

Randomized trial reveals flare profile changes based on spectral type in stellar atmospheres, indicating physical processes.

Key Points

  • This research aims to analyze the shape of light curves from stellar flares detected by TESS to uncover physical processes in stellar atmospheres.
  • Analyzed TESS light curves from five years of data, identifying 120,000 stellar flares.
  • Utilized a recurrent neural network combined with manual vetting for flare identification and classification.
  • Employed dimensionality reduction techniques to explore variations in flare shape profiles based on spectral type.
  • Identified continuous changes in average flare profiles correlated with different stellar spectral types.
  • Revealed that these trends only emerge when averages are taken from thousands of flare events.
  • Demonstrated applications of dimensionality reduction in characterizing flare shape space.
